Donald Trump has given his first public reaction to the prospect of the former Mayor of Greater Manchester Andy Burnham becoming prime minister.

Campaigning during the Makerfield by-election, Burnham said the UK needed to avoid what he called the “polarised, poisonous politics” of the US.

Asked his view of the current frontrunner to replace Sir Keir Starmer, Trump described him as “the mayor of a town” and said he had heard Burnham was “extremely liberal”.
