Britain's foreign minister will host European peers on Monday to discuss support for Ukraine and greater regional defence cooperation in the run-up to Prime Minister Keir Starmer's summit with European Union leaders next week.

Axar.az reports, citing Reuters, UK Foreign Secretary David Lammy was due to hold talks with representatives of France, Italy, Germany, Spain, Poland and the EU, Britain's foreign ministry said.

"We are facing a once-in-a-generation moment for the collective security of our continent," Lammy said in a statement. "The challenge we face today is not only about the future of Ukraine - it is existential for Europe as a whole."

Lammy planned to announce further sanctions targeting actors supporting Russia's invasion of Ukraine, the statement said.

Lammy would use Monday's meeting to press Britain's calls for a strengthening of European security, the ministry said.
