While candidates were making a last-ditch pitch to floating voters, political sway of a different kind has been causing problems for one party's mobile billboard.

UKIP's travelling poster van - adorned with the face of party leader Nigel Farage - was today temporarily retired from the road on health and safety grounds, after high winds made it too dangerous to drive.

Party bosses had intended for it to circle Norwich for 10 hours today as part of their late push to convice undecided voters, but said the setback wouldn't blow their election plans off course.

A UKIP spokesman said: 'Health and safety, in these circumstances, is right and proper. It's red tape but we have to be compliant with the law.

'We know there's a level of floating voter in Norwich South and we will be working very hard to get to them tomorrow.'
