Tommy Sheridan is contesting the Glasgow South West seat
The Trade Unionist and Socialist Coalition (TUSC) is contesting 42 seats across the UK, as well as 10 in Scotland.
Its candidates include former Solidarity MSP Tommy Sheridan.
The party says Labour has become a party of big business, leaving trade unionists disenfranchised.
Their manifesto outlines the grouping's opposition to all cuts in public services and it also calls for the privatised utilities to be brought back into public ownership.
The group is opposed to the privatisation of Royal Mail and is urging the repeal of what it describes as anti-trade union laws.
They have pledged to fight for the interests of the pensioners, the sick, the unemployed, the poor and working class communities.
Bob Crow, leader of the GMT rail union - who is backing the coalition - said they were the only ones putting forward a pro-union, pro-worker programme instead of the cuts, privatisation and deregulation offered by the other parties.
