Sir Keir later said the UK would “play its full part” and welcomed the lead the US is taking on peace negotiations during a call with G7 leaders including Mr Trump, whose overtures to the Russian president have alarmed Ukraine’s allies.
Sir Keir Starmer has previously said he would be willing to put British troops on the ground as part of security guarantees that could end the war between Russia and Ukraine.
Sir Keir said a new package of UK sanctions will target Russia’s so-called shadow fleet, used to transport oil and goods in defiance of sanctions, as well as companies in China and elsewhere providing Moscow with military components.
Addressing reporters alongside Mr Macron, Mr Trump said of the Russian president’s reaction to peacekeepers in Ukraine: “Yeah, he will accept it.”.
It comes on the third anniversary of Russia’s invasion, as Sir Keir imposed further sanctions on Moscow in an attempt to force Mr Putin “not just to talk, but to make concessions”.
