[15] In July 2020, after Jeremy Corbyn stood down, the Socialist Party called for the relaunch of the alliance;[16] in September of the same year, the TUSC steering committee agreed to resume standing candidates in the 2021 UK local elections.

[18] At the March 2009 Socialist Party congress, RMT executive members Alex Gordon and Brian Denny addressed Socialist Party delegates in an official capacity, outlining the RMT's proposal for workers' slates in the European elections in June.

[20] The Socialist Party stated it "would prefer a name that includes 'socialism', for marked ideological contrast to New Labour, and also one that makes it clear that the coalition is a working class alternative.

[29] TUSC chairperson Dave Nellist stood as a candidate for the coalition in the constituency of Coventry North East.

Among the other candidates were Jackie Grunsell in Colne Valley constituency, Keith Gibson in Hull West and Hessle, Dave Hill in Brighton Kemptown, Ian Page in Lewisham Deptford, Rob Williams in Swansea West and Tim Cutter in Southampton Itchen.

[33] In July 2020, the Socialist Party called for the relaunch of the electoral alliance[16] and in September the TUSC steering committee agreed to resume standing candidates in the 2021 UK local elections.

They had agreed that, “in the new conditions of a Starmer leadership and the continued implementation of austerity cuts by many Labour-led authorities, we believe it is correct for TUSC to lift its suspension of electoral activity”.

[40] In 2022, under newly elected General Secretary Sharon Graham, Unite responded to TUSC's invitation and formally deputised the union’s Lead for Local Government, Onay Kasab, to TUSC's annual conference on Sunday February 6 to 'explain the extremely significant decision of [Unite's] recent policy conference to call on “Labour councils to set legal, balanced no cuts needs based budgets” rather than meekly accept the Tories’ austerity agenda', which echoed a policy position of TUSC.

[41][42] Previously, in February 2015, senior figures from Unite the Union condemned the Socialist Party and by implication TUSC, for standing candidates against Labour in marginal constituencies for the 2015 general election.

[43] In response, the Socialist Party claimed that a Labour government "would be at best austerity-lite and a continuation of the crisis that faces working class people".

[27] Each of TUSC's constituent organisations is entitled to have representatives on the All-Britain Steering Committee, where they engage in decision-making regarding policy, strategy, and the selection of candidates.

After the defeat of Labour in the 2019 election and the replacement of Corbyn as leader by Keir Starmer in April 2020, TUSC has decided to lift its suspension of electoral activity.
