Wiltshire Council has apologised and promised a review after some Devizes electors may have been disenfranchised because they couldn’t find their polling station, local activists say.

A spokesman for Wiltshire Council said: “Despite our best efforts, and as a result of the boundary changes, some polling stations were not situated as conveniently as we would have liked.

“We will be reviewing all aspects of the election.”

Judy Rose, secretary of the Devizes Guardians, the group whose candidates took three of the four council seats in Devizes in last week’s election, said she had been approached by one voter at the town hall who wanted to vote there because he couldn’t find the polling station at the Cadet Centre on the former Le Marchant Barracks site.

She said: “I had to draw a map for him on his polling card. I understand that he was not the only voter who turned up there with a similar inquiry.”

The Cadet Centre can now be approached only by driving through the Le Marchant estate. There are no signs for it on any approach roads.

Before the election, Guardian candidate Ted East, who lost out to Tory Laura Mayes in the Roundway ward, wrote to electoral services officer John Watling raising concerns over the siting of the only polling station for Roundway, on the north of the town. Mr Watling said he would look at the situation after the election.
