Delegate boost for candidate Romney

Republican presidential candidate Mitt Romney has picked up nine more delegates, winning unanimous backing at the Republican convention on the US territory of Guam.

Republicans on the tiny Pacific island decided to shun traditional paper ballots, and all 215 eligible to vote at the state convention backed Mr Romney with a show of hands.

The Guam convention's co-chair, Jerry Crisostomo, said that while Guam's Republican National Convention delegates are technically uncommitted, all nine have pledged to vote for the candidate chosen at the state convention.

Mr Romney's son Matt attended the event, which took place in Guam.

A day earlier, Matt Romney visited the neighbouring Northern Mariana Islands. It too has nine delegates and Republicans are set to vote there this weekend as well.
