The meeting took place on May 12 (local time), in preparation for the summit between Prime Minister Keir Starmer and the leaders of the European Union next week.
The meeting will be attended by representatives from France, Italy, Germany, Spain, Poland and the European Union, according to the British Foreign Ministry.
Foreign Minister Lammy stressed that this is a turning point for the collective security of the continent: The challenge we are facing today is not only related to the future of Ukraine, but also a vital issue for all of Europe.
Lammy is expected to announce new sanctions against individuals and organizations accused of supporting Russia's conflict in Ukraine.
Earlier, on May 10, leaders of the UK, France, Germany and Poland visited Kiev to express their support for Ukraine's proposal for a 30-day unconditional ceasefire. The leaders also warned Russian President Vladimir Putin that if he does not accept it in the next few days, he could face " stronger" sanctions.
In response, on May 11, Mr. Putin proposed holding direct talks with Ukraine to end the conflict, although he did not immediately agree to the ceasefire request before the dialogue.
British Foreign Minister Lammy plans to take advantage of the May 12 meeting to emphasize the UK's call for strengthening European security amid prolonged instability in the region.
At a summit with European Union leaders on May 19, Prime Minister Keir Starmer set a goal of reaching a new defense deal with the bloc while improving trade relations after Brexit.
The summit is expected to mark the beginning of a period of deeper cooperation between the UK and the EU, in the context of geopolitical changes reshaping security and economic alliances in Europe.
