Downing Street said the deal would bring together "Ukrainian expertise and the UK's industrial base" to manufacture and supply drones and other capabilities. Their meeting comes as the US-Israeli war with Iran enters a third week, during which US President Donald Trump has criticised the UK and other countries over the extent of their response to the conflict. Under the partnership between the UK and Ukraine, closer co-operation in the defence industries will also be sought with third countries as part of efforts to bolster international security. Britain will also give £500,000 to fund an AI centre of excellence in Kyiv. "By deepening our defence partnerships, we are strengthening Ukraine's ability to defend itself from Russia's brutal, ongoing attacks, while ensuring the UK and our allies are better prepared to meet the threats of the future. Zelensky is currently on a tour of European capitals to shore up support and keep his conflict at the forefront of allies' minds.
