John McCain backs Mitt Romney for the White House

The race to become the Republicans' Presidential candidate has started with the narrowest of victories for the former governor of Massachusetts, Mitt Romney.

He finished just eight votes ahead of the Christian conservative Rick Santorum - who garnered a last minute surge in support in the rural Midwest state of Iowa.

The race now moves on to next Tuesday's vote in New Hampshire.
