Sir Keir Starmer and Emmanuel Macron will host a meeting of the coalition of the willing when the French president visits Britain next week.
The Prime Minister and France’s leader will dial into a meeting with allies on Thursday, as Mr Macron makes his first state visit to the UK, it is understood.
Britain and France have led efforts to establish the coalition, a peacekeeping force aimed at policing any future ceasefire deal in Ukraine, and deterring further threats by Russia.
The effectiveness of the coalition has been called into question, as only London and Paris have so far indicated they would provide frontline soldiers towards it.
The peacekeeping mission would also be predicated on American air support, something which US President Donald Trump has been unwilling to openly say he would provide.
