 U.K. will transfer to Ukraine the largest batch of UAVs in history. The United Kingdom will provide £2.5 billion of military aid to Ukraine over the coming year. British Prime Minister Rishi Sunak has said Britain's largest annual commitment since Russia's invasion. The British Prime Minister made a surprise visit to Kiev. After signing a U.K.-Ukraine Agreement on Security Cooperation, the U.K. may provide intelligence sharing, cybersecurity, medical and military training and defense industrial cooperation. The U.K. will also provide £2.5 billion in military aid to Ukraine in 2024-25, an increase of £200 million on the previous two years. About £200 million will also be spent on a push to procure and produce thousands of military drones. It will be the largest delivery of drones to Ukraine, from any nation according to Downing Street. Most are expected to be manufactured in the U.K. The package will also provide the country with long-range missiles, air defense, artillery ammunition and maritime security. The Ukrainian president has said his forces particularly need air force systems to fend off Russian aerial barrages. More than 500 drones and missiles were fired between 29 December and 2 January, according to officials in Kiev. The agreement comes as the Ukrainian president presses allies in the west to provide the country with more support to fight back against Vladimir Putin's Russian forces amid fears that interest in the war is flagging as the conflict drags on.
