Presidential contender Donald Trump has come under attack from his rivals at a Republican debate, after a day in which the party’s veteran politicians urged voters to desert him.
The front-runner in the Republican race was on the defensive in Detroit as Marco Rubio and Ted Cruz piled in.
In a testy debate, Mr Trump admitted he had changed his stance on issues but said flexibility was a strength.
Senior Republicans say Mr Trump is a liability who would lose the election.
The debate began with Mr Trump being asked about an attack earlier in the day by Mitt Romney, the 2012 nominee, who accused the businessman of bullying, greed and misogyny. Mr Trump dismissed Mr Romney as a “failed candidate”.
Ohio Governor John Kasich was the fourth Republican contender to take part in Thursday’s debate.
Leading the attack on Mr Trump, Florida Senator Marco Rubio said he was “not going to turn over the conservative movement to someone who thinks the nuclear triad is a rock band from the 1980s”.
In one of the most bizarre moments, Mr Trump defended the size of his hands and then quipped about another part of his anatomy.
There were plenty of personal insults from Mr Trump, who labelled the Florida senator “little Rubio” and the senator from Texas as “liar Ted”.
