US elections: Gingrich suspends presidency bid

3 May 2012 Last updated at 06:21 BST

Newt Gingrich has formally ended his presidential campaign, but fell short of an endorsement for presumptive Republican nominee Mitt Romney.

He said November's election offered a choice between Mr Romney and Barack Obama, "the most radical, leftist president in American history".

Mr Gingrich ends his campaign some $4m (£2.5m) in debt, according to reports.
