It was initially known as the People's Labour Party, and stood their chair, Jim Hamezeian, in the Barrow and Furness constituency in the 1997 general election.

However, in the 2006 local elections, party leader Jim Hamezian regained his seat in the Ormsgill ward.

[1] After that, the party's support dropped: in the 2010 local elections the SPP lost two councillors, and lost all representation on the Borough council in 2011 local elections.

The SPP retained one councillor on Cumbria County Council until the May 2013 elections, when they lost all representation.

The party deregistered with the Electoral Commission in 2015 and its website is no longer active.
