Hyndburn has been identified as an area at 'greater risk' of electoral fraud.
Out of 400 local authorities in the UK the Electoral Commission has identified 16, including Hyndburn, as areas of concern.
The report said: “The evidence and views we have heard raise significant questions about whether individuals within these communities are able effectively to exercise their right to vote, and whether they are able to participate in elections on the same basis as other electors across the UK.”
The report continued: “Sustained action is needed especially in those areas where there is a higher risk of allegations of, or attempts, at electoral fraud, both to minimise the risk of further allegations and to respond effectively if allegations or attempts at fraud do arise.”
The report has made three recommendations to root out fraud in areas like Hyndburn.
These include strengthening the police presence on election days, restricting the involvement of campaigners in vote counting and introducing the requirement for voters to produce ID at polling stations.
Jenny Watson, Chair of the Electoral Commission, said: “Proven cases of electoral fraud are rare and when it is committed, the perpetrators tend to be candidates or their supporters. “Voters are the victims and sustained action is needed now to prevent fraud from taking place.”
A Council spokesperson said “As in previous years we will continue to take all the steps we can to prevent electoral fraud in the borough.”
Other areas highlighted in the report include Pendle, Blackburn with Darwen and Burnley.
