About 1,500 voters in Swindon have been mistakenly warned that they may not be able to vote in the general election.
In a letter sent by Swindon Borough Council residents were told they would be “removed from the Register of Electors” as they were “not entitled to remain registered” at their property.
Residents were given 14 days to appeal against the move.
The council has since tweeted asking residents to ignore the letter as it was sent “by mistake”.
The letter, dated 4 November, said the council was reviewing its “registration entitlement” and it was the authority’s “opinion” that the resident was “not entitled to remain registered at this property”.
Residents were warned that if they did not appeal against the decision they would be removed from the electoral register.
