GMB is one of the three largest affiliates of the
Labour Party. It is a significant financial contributor to the party's national and local organisation.
The Guardian reported in 2012 that GMB gives Labour up to £2 million a year in affiliation fees and other funds, making it the third largest union donor to the party. In 1991, GMB was the first British trade union to set up an office in Brussels and has been particularly engaged in seeking to influence
European Union legislation that sets minimum standards for workers and for health and safety across the EU single market. In 2008, GMB Congress voted to withdraw local funding from around a third of the 108 Labour MPs whose constituencies received support from GMB, due to the perception that some MPs within the party were treating workers with "contempt" and generally not working in the interests of the working class and GMB members. Despite this the Congress opposed disaffiliation from the party. In the
2010 Labour Leadership Election, GMB endorsed
Ed Miliband over his competitor and brother
David Miliband. In 2013, GMB announced it was cutting its affiliation fund from £1.2 million to £150,000 by reducing the number of members it affiliates from 420,000 to 50,000. In 2013, GMB Congress, the lay member ruling body, adopted a 14-point plan to encourage GMB members to become active in the Labour Party and to stand as Labour candidates for public office (Parliament and local government). GMB has two representatives on the
National Executive Committee (NEC) of the Labour Party, Kathy Abu-Bakir and Gavin Sibthorpe. In Ireland, GMB is affiliated to the Irish
Labour Party. While in the
2015 Labour leadership election GMB did not endorse a candidate, in the
2016 Labour leadership election, the union endorsed
Owen Smith against incumbent leader
Jeremy Corbyn. Under the leadership of
Jeremy Corbyn, the GMB clashed with the party over the issues of
Trident renewal and
fracking, both of which are opposed by Corbyn. In the
2020 Labour leadership election, the GMB endorsed
Lisa Nandy, who subsequently finished third. == Leadership ==
