The Trade Unionist and Socialist Coalition (TUSC) was set-up in 2010, co-founded by the late Bob Crow, with the primary goal of enabling trade unionists, socialists, and working class social movement and community campaigners to stand candidates against pro-austerity establishment politicians.
Candidates who want to stand under the TUSC banner have autonomy to run their own campaigns. The only provision is that they are expected to endorse the TUSC core policy platform for the relevant election, which are discussed at TUSC conferences subject to the final agreement of the TUSC steering committee, encompassing the different component parts of the coalition (see How TUSC functions at https://www.tusc.org.uk/wp-content/uploads/2023/04/How-TUSC-Functions-September-2022.pdf).
The individual candidates and different organisations appearing on the ballot paper under the TUSC name and logo will almost certainly campaign for and promote far more issues than those covered in the core policies agreed for each election. That’s what being a coalition is about.
But what they will all do is fight to implement the core policies. Voters will know the minimum they can expect from any representative elected under the TUSC banner.
