Mitt Romney focuses on President Obama after wins

Mitt Romney has taken a stride closer to the Republican presidential nomination by winning primaries in Wisconsin, Maryland and Washington DC.

He routed his main rival Rick Santorum in Maryland, although his projected margin of victory looked leaner in Wisconsin.

Mr Santorum, who has faced calls to bow out of the race in the name of party unity, defiantly vowed to fight on.

The eventual winner will face Barack Obama in November's election.

Steve Kingstone reports.
