Great Britain has so far refused to send troops to Ukraine. Former British Armed Forces Secretary James Heappey called for Britain to reconsider that stance.

French President Macron initiated the debate with his move not to rule out the possibility of sending troops. British troops have already caused speculation in the context of the Ukraine war in February after a meeting of senior Bundeswehr officers was intercepted and leaked. A spokesman for British Prime Minister Rishi Sunak said publicly in February that "a small number of forces were in the country supporting Ukrainian forces" The security agreement that Sunak agreed with Ukrainian President Volodymyr Zelensky in January includes areas such as cybersecurity, military and medical training and cooperation in arms production, as well as the sharing of intelligence information. The agreement should be in force until Ukraine can join NATO. However, it is valid for a maximum of ten years. UK is one of Ukraine's main supporters in its defense against Russia. NATO Secretary General Jens Stoltenberg recently confirmed that there are no plans to deploy NATO troops in Ukraine. Russian President Putin has in the past strongly warned Western states not to sent troops into Ukraine.
