It has been reported that Thanet District Council sent polling cards to 11,500 people that stated they were electing an MP for a neighbouring constituency.
The cards were sent to residents in South Thanet and said they were choosing a member of parliament for the North Thanet constituency on 8 June.
The villages affected included: Ash; Goodnestone; Preston; Sandwich North and South; Staple; Stourmouth; Wingham; Woodnesborough, and Worth.
The authority put the mistake down to a clerical error and confirmed it should have read South Thanet.
New cards have been sent out with an explanation and an apology.
The council assured: ”The mistake will not impact on anyone's ability to vote.”
