Under the influence of a faction of the Communist Party of Turkey, a handful led by NCP youth section leader John Chamberlain (who uses the pseudonym Jack Conrad) attempted to rejoin the then CPGB.

The attempt failed as the ISG collapsed and Open Polemic briefly enrolled a few of its supporters in the CPGB (PCC), only for them to quit in a row over money.

[citation needed] During the 1992 general election campaign, Ken Livingstone claimed that the members of the CPGB (PCC) were "MI5 agents".

The CPGB (PCC) endorsed the Labour Party in the June 2009 European Parliament elections and criticised the No to EU – Yes to Democracy coalition as "left-wing nationalist".

Non-members such as former Soviet dissident Boris Kagarlitsky, Matzpen founder Moshé Machover and Professor Hillel Ticktin, editor of Critique and chairman of the Centre for the Study of Socialist Theory and Movements, University of Glasgow, have spoken at CPGB (PCC) events.

[16] A minority of members objected to the dissolution of the campaign including in published articles by Dave Spencer,[17] Phil Sharpe[18] and Steve Freeman.

They accused the campaign's initial appeal of making "Keynesian platitudes"[19] and called for a new formation on the left to have an explicitly Marxist programme.

[24] On 29 March 2014, CPGB member Yassamine Mather was elected to Left Unity's National Council at the party's first policy conference.

Amongst the regular speakers are Scottish computer scientist Paul Cockshott, Iranian scholar and activist Yassamine Mather and a founder of the Israeli socialist organisation Matzpen, Moshé Machover.

Despite its origins in the New Communist Party of Britain, The Leninist advanced sharp criticisms of the Soviet Union and the Eastern Bloc countries while strongly opposing movements it considered to be in support of capitalism.

[33] Today, leading member Jack Conrad calls these societies forms of "bureaucratic socialism"[34] in a view strongly influenced by Hillel Ticktin and the Critique journal[35] while Mike Macnair argues that the Soviet Union was a peasant based society frozen in transition from feudalism to capitalism.

[37] The party formerly listed the abolition of the age of consent among its immediate demands, with alternative legislation to protect children from sexual abuse.

[38] In 2021 it amended this demand: "Young people are entitled to develop their sexual lives free from parental, police or religious control.

"[39] The CPGB (PCC) has informal ties with the Dutch Communist Platform, which shares a similar political point of view.
