A spokesman for the U.K. prime minister, Pares, said London is prepared to deploy a “reassurance force” to Ukraine, underscoring continued military and political backing for Kyiv as the war with Russia grinds on. Details on the size, timing and mandate of the contingent were not released, but officials framed the move as part of broader efforts to deter further Russian aggression. The U.K. also welcomed a new U.S. statement outlining long-term security guarantees for Ukraine and agreed in principle to Washington’s proposal for a trilateral meeting with Ukrainian President Volodymyr Zelensky. British officials said the talks would focus on coordinating military assistance and longer-term security arrangements.
