Lincolnshire County Councillor Colin Mair will fight the Louth and Horncastle constituency for UKIP in next year’s General Election.
Coun Mair’s nomination will be confirmed at a meeting in Horncastle later this month.
The news ends weeks of speculation about the identity of the UKIP candidate.
Several big names were linked with the position but the party has gone for a local candidate.
Originally from South Yorkshire, Coun Mair has lived in the Coningsby area for several years.
He ousted Betty Harvey to win the Tattershall Castle seat in the 2013 County Council elections for UKIP.
A former solider, he is the leader of UKIP on the County Council.
Coun Mair said he was looking forward to the challenge of replacing Sir Peter Tapsell as MP for Louth and Horncastle.
Under Sir Peter, the constituency has become one of the safest Tory seats in the entire country.
Victoria Atkins will be his Tory opponent with Matthew Brown leading the Labour challenge.
