Although performing better in local elections than in general ones, the NF never won a seat on a local council. In October 1969, two Conservative councillors on Wandsworth London Borough Council—Athlene O' Connell and Peter Mitchell—defected to the Front, but returned to the Conservatives in December. In the May 1974 London council elections, the party averaged 10% of the vote in the boroughs of Haringey, Islington, Brent, Southwark, and Lewisham, while its best result was in Hounslow. In the April 1976 council elections, the NF boosted its vote in many towns, securing 21% of the vote in Sandwell, 20.7% in Wolverhampton, 18.54% in Leicester, and 17% in Watford.
