With 12 days until the US election, President Barack Obama and Republican rival Mitt Romney are crossing the country looking for every last vote in crucial election states like Ohio, Virginia and Florida.

But Mr Obama is leading - albeit slightly - in the states that will likely decide this contest.

The BBC's Mark Mardell reports from the Romney campaign trail.
