Mitt Romney: Donald Trump ‘a fraud and phoney’

Donald Trump has come under attack from former US presidential nominee Mitt Romney, who urged fellow Republicans to shun the property tycoon for the good of the country and party.

Mr Romney, who was soundly defeated by President Barack Obama in his 2012 re-election, joins a growing chorus of anxious Republican leaders that many Trump supporters see as establishment figures.

“Here’s what I know: Donald Trump is a phoney, a fraud,” Mr Romney said in a speech.
