Mr Trump was riled by one of the first questions - he was asked if his economic plan was a "comic-book version" of a presidency campaign. Eight other candidates, who remain a long way behind in the polls, used the opportunity to aim their fire at the two frontrunners.

Former Florida Governor Jeb Bush and Florida Senator Marco Rubio traded barbs, with Mr Bush saying the people of Florida deserved a senator devoted to representing them, not one busy running for president.

Analysis - Nick Bryant, BBC News, Boulder
Twin contests played out on the stage in Colorado - a fight to become the candidate of the Republican establishment and a battle to become the standard bearer of the radical right.
In the first contest, Jeb Bush delivered another listless performance that will deeply worry his donors, and a pre-meditated decision to attack his friend and rival Marco Rubio for absenteeism from his day job, as the Florida Senator, backfired badly. It seemed so contrived, as Rubio, a big winner tonight, deftly pointed out.
In the establishment contest, it was the defining exchange of the night, and will enhance Rubio's growing stature and further diminish Bush. The New Jersey Governor Chris Christie also outstripped Bush.
As for a rumble in the Rockies between Donald Trump and the candidate who dislodged him in the polls, Ben Carson, it never unfolded. Trump was low-key - it seemed almost that he is tiring of the process. Carson disappeared for much of the debate.
Perhaps sensing a chance to impose himself, the Texas Senator Ted Cruz delivered an impassioned attack on the moderators of the debate and the media more broadly for its liberal bias. Speaking of his born-again father will have impressed evangelicals. This was the best two hours of the Cruz campaign so far.
But the main headline of the evening comes from Jeb Bush. He needed to energise his troubled campaign tonight, and he failed abysmally.
