At a Cabinet meeting last night, Mr Trump said the minerals deal with Ukraine would be a “very big agreement”.
Asked if Mr Trump also believed that, Sir Keir said: “Of course, the President has been very clear about the peace that he wants.
Ukraine President Volodymyr Zelensky confirmed last night he would attend after his own meeting with Mr Trump on Friday.
SIR Keir Starmer tonight insisted he trusted Donald Trump but warned him Russia would never stop without America protecting Europe.
But Mr Trump repeated his demand that Europe should police any peace deal between Russia and a war-weary Ukraine.
