The coalition of the willing is a coalition of 31 countries which have pledged strengthened support for Ukraine against Russian aggression, going further than the support delivered by the Ukraine Defense Contact Group by pledging readiness to also be part of a peacekeeping force deployed on Ukrainian territory, either by providing troops or contributing in other ways. The peacekeeping force is envisaged only to be deployed the moment Ukraine and Russia sign a "comprehensive ceasefire agreement" or "peace deal" to settle the ongoing Russo-Ukrainian War. The initiative, led by the United Kingdom and France, was announced by British Prime Minister Sir Keir Starmer on 2 March 2025, following the 2025 London Summit on Ukraine under the motto "securing our future".
