 The biggest challenge is capturing data at source. The definition of postal is we don't know who the sender is. And this is particularly true for citizens and for small and medium enterprises. Large companies can deal with it because we know it and they have the right systems. But it's for people around the world who might want to send something to Ireland, how we capture that data is very difficult. It's why a forum like this is so important that the voice of the citizen is heard and the voice of small and medium-sized companies is heard. And that's what I hope we bring to it. Getting together the WCO and GPU is a brilliant idea. Customs is an essential operation for the safety of citizens. Postal is an essential service for the facilitation of trade for citizens. And I always say trade doesn't belong to any one country, trade belongs to a citizen. So having the two together so that we can jointly work out the best way to facilitate trade while at the same time using all of the advances in technology and digital and AI to be able to ensure that we've got a safer and better world.
