The Electoral Commission has sent out an alert to returning officers warning polling staff not to fold ballot papers after talking to returning officers and the UKIP which "raised the issue with them".
What's causing all the fuss is the bottom of the paper being very neatly folded backwards just above the dividing line. On casual inspection this gives the impression that the paper ends there effectively removing the UKIP from the ballot.
A UKIP spokesman is quoted as saying "We are getting literally hundreds of calls saying we can't find you on the ballot paper so we voted for somebody else."
With so many of their supporters seemingly unable or unwilling to ask for assistance it looks like Boris might not be the only one to take an early bath today.
