The war in Ukraine is top of mind for European leaders. 

France is set to host a summit to discuss the situation and European security. 

It comes as the continent tries to respond to US President Donald Trump's unilateral approach to the conflict. 

UK correspondent Gavin Gray told Andrew Dickens European leaders are worried about being left out of negotiations to end the war. 

He says they fear it will be put together by America and Russia - without even involving Ukraine.
