Andrew Feinstein, former ANC MP under Nelson Mandela and leading critic of the global arms trade, will use a speech this weekend to endorse a new political alliance billed as the foundation of the first organised mass movement of the left outside of the Labour Party.

Feinstein’s speech will be the centrepiece of a conference called by dozens of former Labour councillors and other independent candidates. The event will take place in ‘Labour’ leader Keir Starmer’s home constituency of Holborn and St Pancras in London.

Feinstein, who has lived in the constituency for more than two decades since moving to the UK, has already signalled his willingness to stand against Starmer as an independent candidate and has been selected as candidate by the OCISA anti-Starmer group, attracting a groundswell of support both locally and nationally.

Local campaigners say there is real vulnerability in Starmer’s majority, established under Jeremy Corbyn’s leadership of the party, especially given the controversies embroiling Labour over the war in Gaza. Starmer looks even more vulnerable after yesterday’s landslide victory for Workers Party GB leader George Galloway in Rochdale and the collapse of Labour’s vote from over 50% to less than 8%, with Starmer’s support for Israel’s genocide in Gaza a major driver.

The new movement – dubbed ‘Collective’ – has been established following months of deliberation amongst grassroots campaign groups and prospective independent candidates for both council and parliamentary elections. Though it is not establishing a new party in time to contest this year’s election, it intends to do so onceit has grown a mass membership base.

Feinstein said:

It’s not just Labour Party members who were the victims of Starmer’s entirely fictitious campaign for leadership of the party. The people of Holborn and St Pancras also elected him twice on a socialist platform under the leadership of Jeremy Corbyn. Having lived in the constituency for over 20 years, I’ve been overwhelmed by the support and strength of feeling amongst local communities – and across the country – who are crying out for a response to the deeply corrupt, anti-democratic and out of touch Labour Party under Starmer. Under his leadership, the party has now completely abandoned working people and marginalised communities in an escalating effort to out-Tory the Tories.

But this election must do more than just provide an alternative to the pro-genocide, pro-austerity Sunak-Starmer circus. It must also mark the beginnings of a new mass movement of working people that can challenge the Westminster bubble once and for all. That’s why I’m proud to be joining Collective which is uniting sections of the left and will eventually transform into a new political party backed by an organised and democratic movement.

Collective spokesperson Pamela Fitzpatrick, independent candidate for Harrow West:

Our political system – and now the Labour Party itself – is fundamentally anti-democratic and rigged against new parties, especially on the left. The only way to address this is to build a mass movement outside of the Labour Party as a foundation for a new political party that is truly free of vested interests and which can offer a real alternative to the pro-austerity and pro-war two party system. All around the country, independent candidates have and are coming forward to fight this election on a common platform calling for an immediate and permanent ceasefire in Gaza, a real pay rise and decent housing for all, higher taxes for the rich, an end to privatisation of the NHS, and an end to unnecessary and unjust war. That is the foundation which Collective will build on, and eventually transform into a political party that will change the face of British politics.
