Donald Trump has publicly disowned Steve Bannon as the pair fell out spectacularly over a new book revealing embarrassing details about the White House.

The US president said Mr Bannon, who ran Mr Trump’s election campaign and advised him in office, “has nothing to do with me or my presidency”.

Mr Trump claimed his former chief strategist had “lost his mind” and “rarely” met him one-on-one before leaving the White House last August.

The president also accused Mr Bannon of leaking “false information” to “make himself seem far more important than he was”.
