Ukip is using child sexual abuse to try and win votes.
It has caused fury with posters promoting Jack Clarkson, its candidate for South Yorkshire Police and Crime Commissioner.
The poster reads, “There are 1,400 reasons why you should not trust Labour again.”
This refers to a recent report that estimated some 1,400 children had suffered sexual abuse in Rotherham between 1997 and 2013.
The election takes place on Thursday of this week.
Former police officer Clarkson was on duty at Orgreave during the 1984-85 miners’ strike and during the 1989 Hillsborough football disaster.
Meanwhile, a new opinion poll reported that nearly a third of people would vote for Ukip if they thought it had a chance of being elected in their area.
The hard right party won its first MP in Clacton, Essex, last month.
It hopes to win a second in Rochester and Strood when a by-election takes place on 20 November.
