Republican House Speaker 'focused on saving party majority - not Trump win'

America's most powerful Republican has told his party that he is now focused on ensuring Hillary Clinton is not handed a blank cheque as president in a Democratic-controlled Congress - suggesting he does not believe Donald Trump can win the US election.

House Speaker Paul Ryan's office moved quickly to say that he was not conceding the election, but pro-Trump House members insisted the New York billionaire can still win and should not be abandoned.
