Police have charged seven people with fraud in connection with postal voting at the general election two years ago.
Each of the men has been charged with conspiracy to defraud the returning officer in Bradford, West Yorkshire.
West Yorkshire Police said the charges come after a joint investigation with the city's returning officer.
Six are from Bradford and are aged 38, 40, 53 and 67, with two aged 49. The seventh man charged is a 37-year-old from Buckinghamshire.
The investigation looked at voting patterns and postal votes. The cases are due in court on 14 November.
