The Labour Party is different from other mainstream political parties as it is made up of not just party members, but is also composed of affiliated trade unions and socialist societies. These links to organisations outside of the Labour Party are vital in ensuring that the voices of millions of people are given political representation, and makes the Labour Party the political wing of the wider labour movement. 


Trade unions are the largest organised institutions of the working class. They organise and represent workers in their workplaces, and help secure the best deal for their labour.

Some trade unions are formally affiliated to the Labour Party, and as such, have influence over the Party's policy and leadership.  This is represented in the right of trade union delegates to vote at Party Conference and sit on both the Scottish Executive Committee and the National Executive Committee.

CfS fully supports the trade union link and the involvement of trade unionists at all levels of the Party.

The unions affiliated to the Labour Party are:

ASLEF (Associated Society of Locomotive Engineers and Firemen)

BECTU (Broadcasting, Entertainment, Cinematograph and Theatre Union)

BFAWU (Bakers, Food and Allied Workers Union)


CWU (Communication Workers Union)

GMB Scotland

MU (Musicians Union)

NUM (National Union of Mineworkers)

TSSA (Transport Salaried Staffs' Association)

UCATT (Union of Construction, Allied Trades and Technicians)

UNISON Scotland

Unite Scotland


USDAW (Union of Shop, Distributive and Allied Workers)

In Scotland, the Scottish Trade Union Labour Party (STULP) committee helps coordinate the affiliated unions within the Scottish Labour Party.

Across the UK, the Trade Union Liaison Organisation (TULO) helps coordinate the affiliated unions within the UK Labour Party.


There are a range of socialist and co-operative societies which also have formal relationship with the Labour Party, and can also send delegates to Conference and have representatives on the Scottish and National Executive Committees. The following information has been taken from the Labour Party's page on affiliated organisations

Co-operative party

The Co-operative Party is a separate political party but which has an electoral agreement with Labour.  It is the political voice of the British co-operative movement.  Over one billion people are members of co-operatives worldwide which globally employ 250 million people, and generate £1.4 trillion in turnover while providing the services and infrastructure communities need to thrive.
