 Mr Corbyn to quit his party, including from the Home Secretary, Sadie Javid. Some argue it's another blow for a party shrouded in negativity, which seems to be the centre, centering rather on the leader himself. Joining us to discuss this from Westminster is Michael Walker from Mavara Media and writer, Benedict Spence. Hello to you both. Thank you very much indeed for joining us. Benedict, to you, first of all. What do we make of these latest comments from the Labour leader? Well, I don't really think it changes anything. I mean, we already knew that he took part in this wreath-laying ceremony. He had admitted as much in his article in the Morning Star in 2014. To then come out this afternoon and say as he has that he doesn't think he took part in the ceremony, I mean, it's just preposterous. The photograph of him taking part in the ceremony was already in the public domain. To then come out and be so dishonest like this, I mean, it's just...it just begs his belief really. Michael, I mean, we can see him with his hand on the wreath and he says he wasn't sure if he took part in the wreath laying itself. Bit of awks. Well, I think we need to take a step back and look at what was the context of this ceremony. So Corbyn was invited to Tunisia in 2014 by the president of Tunisia to go to a conference, which was bringing together different voices from Palestine to try and create unity among the Palestinian parties and the Palestinian factions so they could better negotiate peace with Israel. The main part of the ceremony was commemorating 45 people or 45-plus people who were killed in 1985 by an Israeli airstrike on the offices of the PLI, the Palestinian Liberation Organization. They were the official representatives, the internationally recognized government in exile of Palestine at that period in time. It seems that what happened was as part of that ceremony there were also wreaths laid for other members of that Palestinian movement, in this case this guy was a terrorist. Corbyn seems to have been unsure whether or not he was laying a wreath on that guy's grave. I mean, what's key is why was he there? He was there to commemorate the death of 45 people who were the recognized government in exile who were bombed in 1985 by Israel. I think that's something we should actually celebrate. Benedict, is that a reasonable wrap up for you then? Well, no, not really because I mean in the article itself he states that he knows that he is also commemorating the deaths of three people killed by the Mossad in Paris in the early 90s. And to then talk about him being at an event to promote unity amongst the Palestinian peoples. I mean bear in mind that Hamas and other militant organizations have gone to war with fatter in the past and done appalling things to members of their own side. I don't really think that you can then say that this event was in any way promoting peace given that he was commemorating people involved in the worst kind of violence. If he actually wants to talk about some sort of unity, why was he at this event? But as far as I'm aware, has never been to an event honouring the people who were killed at Munich by these terrorists. It just doesn't really stand up to scrutiny for me. Michael, I mean, we've heard from the widow of Josef Romano, who was a champion weightlifter. He was castrated and then shot dead by the Munich terrorists. Ilana Romano says that Mr Corbyn is a danger. I think obviously that's incredibly tragic and I send my condolences to that widow. I think as I've said before, we need to look at why Corbyn was at this ceremony. The ceremony was not to commemorate specifically some people who committed a terrorist attack in Munich. This event was to commemorate primarily the 45 people who were killed, 45 civilians, part of a government in exile and to take part in a conference which we're trying to bring together different factions in Palestine. I think the comment made previously was completely incoherent, the idea that why would you have a peace conference between two groups which have been fighting each other? I mean, that's precisely why you have a peace conference. The point is that Hamas and Fatah have been at war. If you both speak at once, then no one can hear what you're saying. Just finish your point, please, Michael, and then we'll bring in Benedict. My point there was that the idea that because Hamas and Fatah were at war, it was illegitimate to turn up to a peace conference that was trying to bring them both together. I mean, that's why you have a peace conference. That's why Jeremy Corbyn was there and that's why he was talking to two different groups that have a very complicated, difficult past. As everyone who's been involved in any peace negotiations before would know, you have to deal with it. You made your point, Benedict, go. That is certainly true, but what he completely fails to address, as he often does, is the fact that this isn't an individual partnership. Hamas has been involved in the murder of Fatah members, which you couldn't really say has been reciprocated in the same way, but back onto the original point, which is why he was there, looking at the broader context of why he was at this ceremony. He knew that these people were being commemorated. He's being photographed laying a wreath on the graves of these people, and I refuse to believe that he wasn't aware who they were. He was stood in front of their gravestones. He must have known who they were. He was standing in front of their gravestones. You can't just say that because he was there as part of a broader thing, there's nothing wrong with pulling out of that or refusing to be photographed in front of that grave specifically. Presumably there were plenty of other memorials to other people murdered in other cases. Why specifically this one? Michael, I mean, if he didn't know, he should have known, surely. Jeremy Corbyn was attending a ceremony organised by the PLO, organised by the Tunisian president. This was not a fringe event. It was an intimate event which was trying to bring together different parties in Palestine and commemorate people that had died in the Palestinian liberation struggle. Some of those who had died were civilians, and some of those who died were terrorists, and, yeah, he should not have been laying a wreath at that grave, but I really don't think that's the primary reason he was there. And I think the reasons he was there not only are legitimate but should be celebrated. There's a reason these stories aren't being written about any other politician, which is that Jeremy Corbyn is incredibly rare in that he genuinely cares about international politics, and he genuinely cares about people who are oppressed. There's a reason why Jeremy Corbyn is there and Ed Miliband wasn't. It's because only Jeremy Corbyn is really genuinely interested in peace in the Middle East and the liberation of the Palestinians. Might as well say something. If you're involved in international politics, you know, sometimes you'll find yourself in a room, or in this case a graveside, with people that have done dreadful things. Absolutely. But why lie? Why lie about it? He started off by saying that he didn't know who they were. He obviously knew who they were in the first article that he wrote in The Morning Star in 2014. He's lied about it, and then even after the photograph has come out that you can see on your screens, even after this has been published, he has come out and says he doesn't think he took part in the wreath laying ceremony. Now, actually, what does this say for a man who wants to be Prime Minister of this country, that he is there at an event honoring the deaths of three terrorists involved in the murder of Israeli athletes in the Munich Olympics? And not only has he not just come out and said, yeah, I was, he's then lied about it, even though it's now in the public sphere. Can this man be Prime Minister? Is he fit to be Prime Minister? I don't think he is. Of course, that's for the voters to decide. But I think a lot more people would probably respect him a bit more if he'd just been honest about it, if he'd just owned up to it, rather than continue, as he has, to try to backtrack and to try to cover his tracks. Michael seems like a reasonable point, no? To be honest, I haven't compared precisely the two different press statements. I think the first one was saying that the reason Jeremy Corbyn was there was to commemorate the 45 people who were killed when the PLO was bombed. And what's emerged now is that he was also at the wreath ceremony where it was laid at this terrorist's grave. I think the idea that you can look at that picture and it's patently obvious what grave he was at is ridiculous. I mean, I look at that grave, I don't know who he's commemorating at that point. And so I think the idea that you could find out afterwards that it could emerge afterwards who you were commemorating at each different grave that you visited. Remember, this is the national cemetery of the Palestinians in exile. So this has everyone who's died, who's Palestinian in Tunisia for the last 50 odd years. You know, he's not going to know the precise personal histories of everyone who is buried. But I think Benedict's point is that, you know, if he wants to be the leader of this country, he should know. He should know which grave he's posing in front of with a wreath. So Jeremy Corbyn was a backbench MP. He was someone who was deeply involved in the Palestine liberation struggle and he was there in solidarity with that movement. There you go. You say he's, but if he was deeply involved then he should know whose grave it was, no? I mean, I think that's asking quite a lot of someone who is a backbench MP who is there in solidarity as part of a parliamentary delegation. I'm sure that now he's a leader of a political party and he's aiming to be Prime Minister. There will be plenty of people researching every specific place he ever stands. But in those days, there wasn't. He was someone who would turn up to many a demonstration because he believed that the people he was there to support were subject to some kind of injustice. And that means sometimes he's going to have stood next to people with complicated past, sometimes people with horrific past. I think we'll look at his history and say that on the whole he has been someone who fights for just causes. Backbench MP, leader of the opposition, man on the street, who on earth takes the time to go to an international event outside his own country and layer wreath at somebody who he doesn't know who it is. Who on earth does that? Well, I've already explained the reason why he was there. So he was there because he was invited by the president of Tunisia to take part in a meeting which was bringing together different factions in Palestine to try and make it more possible to come to a peace agreement with Israel. Now, I agree that's not a normal thing that British citizens do. That's actually why I have so much respect for Jeremy Corbyn and why I think his supporters and the general public see him as an unusual politician who stands up for what he believes in. He has a deep interest in all the liberation movements around the world in a way that not many politicians do. And I think we should celebrate that, not see that as a reason to have a cloud of suspicion over his head. OK. Guys, we're almost out of time. Brief thoughts before we end. Do you first spend it? What should happen next? Well, I don't think anything should happen next. I mean, from my perspective politically, I think he should resign, I thought he should have resigned a very long time ago. From his perspective, why should he resign? This isn't going to affect any of the people that are going to vote for him. They're still going to vote for him anyway. It's entirely up to him whether or not he decides to act on this. I don't think he will. OK. Michael? My advice to the Labour leadership in the press offices would be to stop taking this in a sort of case-by-case basis. So there's going to be plenty awkward pictures that keep emerging over the next three years. I think what the Labour Party should start to do is say we are proud of Jeremy Corbyn's history for standing up for the oppressed around the world. Yes, that means he's sometimes been in complicated company. But on the whole, we know that this is someone who, unusually for a British politician, has spent his life devoted to achieving international peace and justice. OK. Good to talk to both of you. Thank you very much indeed for joining us on Sky News. Thank you. Let us know your thoughts on that or indeed any of the stories that we're covering here on Sky News this afternoon. You can tweet me directly if you would like to at K-Burley. Now around 20 white nationalists marched outside the White House last night a year on from a deadly rally in Charlottesville in the US.
