In further remarks to Sky News, the UK’s former representative to Nato, Sir Adam Thomson, said Mr Zelensky appeared to be preparing domestic audiences for compromises, while “making opening moves” in a likely extended negotiation with Mr Trump over which line to take with the Kremlin.

An offer of NATO membership to territory under Kyiv’s control would end “the hot stage of the war” in Ukraine, but any proposal to join the military alliance should be extended to all parts of the country that fall under internationally recognized borders,

Ukrainian President Volodymyr Zelensky says he wants to work “directly” with US President-elect Donald Trump and is open to his ideas, highlighting Kyiv’s eagerness to keep its most important ally onside as Russia intensifies its attacks.
