A Labour member who heckled Sir Keir Starmer's party conference speech on Wednesday is a former candidate for a far-Left party, it has emerged.

       Carole Vincent shouted from the audience as the Labour leader laid out his vision for the future of his party.

       The 67-year-old carer from Leytonstone, east London, was a candidate for George Galloway’s Respect Party in a 2008 council election, raising questions about how she had been allowed into the conference as a Labour member.

       Other members who have campaigned or voted for other parties, including Tony Blair's former spin doctor Alastair Campbell, have been automatically expelled from Labour.

       Ms Vincent, who appeared on the 2007 series of Big Brother, called out several times during Sir Keir's speech, prompting him to say: "Shouting slogans or changing lives?"

       She said she was angry with the Labour leader for moving the party to the Right, telling The Telegraph: "He doesn't represent the roots of the Labour movement and party.

       "On my membership card, it says I am a member of a democratic socialist policy. People have been shut up."

       After the leader's speech, party members in the conference hall sang the Labour anthem The Red Flag. Some near Ms Vincent pointed at her as they sang the song's lyric about "traitors".

       Other heckling was orchestrated by a hard-Left group founded to oppose the expulsion of Corbynites from the party, The Telegraph can reveal.

       Several people shouted "￡15 an hour", a reference to a row over Labour's position on the minimum wage, while others sang "Oh, Jeremy Corbyn". Another held up a sign reading: "No Purge."

       Labour splinter group Defend the Left said it had placed activists in the audience to wave red cards at Sir Keir and disrupt the flow of his speech. The group also recruited Labour delegates outside the Brighton conference to join their protest.

       Labour's ruling National Executive Committee has decreed that Labour supporters who are also members of some groups campaigning against expulsions from the party should themselves be expelled.

       Tina Werkmann, the founder of Defend the Left, told The Telegraph: "We have been telling people to speak up against Keir Starmer. This is the most vicious attack on the Left for decades, if not ever, in the Labour movement."

       Ms Werkmann also runs Labour Against the Witchhunt, the most high profile group campaigning against the expulsion of members on anti-Semitism charges.

       Defend the Left organised an event in Brighton on Wednesday at which members gave speeches in front of a Corbyn-era "for the many, not the few" banner.

       Graham Bash, 72, a member of the group, said it was "deeply offensive" that many socialists in the Labour Party had been accused of anti-Semitism, adding: "There is a deep anger in the party."

       Other Corbynites in the conference hall said they protested against Sir Keir because he had rejected calls from trade unions to support a ￡15 minimum wage.

       "He doesn't believe in anything – he doesn't listen to women and he doesn't listen to any of his members," said Jessica, 35, from Tottenham, north London. Adam Huckerby, 23, said: "He's Blair without the flair. The speech was unnecessarily long."
