Donald Trump's Ukraine envoy Lt Gen Keith Kellogg is leaving the role, it has emerged hours after a US plan to end the war leaked. Lt Gen Kellogg, 81, is expected to step down as US special envoy in January in a departure that will deal a hammer blow to Kyiv's diplomatic efforts to end the war on favourable terms. The retired general has been a key advocate for Ukraine inside the Trump administration at a time when the White House's support for Kyiv has dwindled. News of his resignation came just hours after an unfavourable draft agreement to end the war was leaked to the media. Under the US proposal, Ukraine would be forced to give up all of its territory in the eastern Donbas region and slash the size of its military in half.
