Bachmann claims victory in Iowa straw poll

Michele Bachmann has narrowly won a straw poll in Iowa as the race to become the Republican presidential candidate for 2012 gathered pace in the US.

It comes five months before the first official Iowa primaries in the race for the White House.

National front-runner Mitt Romney did not actively take part in the Iowa contest and neither did Texas Governor Rick Perry, who announced his candidacy on Saturday.
