London talks aimed at securing a ceasefire between Ukraine and Russia have been downgraded and will no longer include US Secretary of State Marco Rubio and special envoy Steve Witkoff. Rubio intends to delay his visit to UK.

Trump envoy Keith Kellogg will lead the US delegation instead, BBC reported.The meeting on Wednesday will instead be held between senior officials from the United Kingdom, France, Germany, Ukraine, and the United States, with UK Foreign Secretary David Lammy hosting a bilateral discussion with his Ukrainian counterpart.

The negotiations came amid allegations of a possible agreement allowing Russia to keep occupied Ukrainian regions, including Crimea, which Ukraine firmly rejects. President Zelensky has asked for an unconditional cease-fire as a first step, according to BBC.

The pace of diplomatic efforts to end the war is increasing, but nothing is known about where they are going or whether they will succeed.
