The Prime Minister spoke to the President of the European Council, the President of the European Commission and the leaders of Canada, Turkey, Norway and Iceland this morning.
The Prime Minister applauded the progress the European Union had made at the European Council yesterday, saying it was a historic step forward and another sign of Europe stepping up.
Closer collaboration between the European Union, its partners and our combined defence industrial base was vital as Europe stepped up to counter egregious Russian aggression, the Prime Minister added.
Updating on the intensive diplomacy between the US, UK, France and Ukraine, the Prime Minister welcomed the potential for peace talks in Saudi Arabia next week.
The leaders also discussed the Coalition of the Willing and looked ahead to the Chiefs of Defence meeting in Paris on Tuesday. It would be another important moment to drive forward planning, they agreed.
The leaders agreed to stay in close touch.
