She added: "I am a fighter. I've fought a few battles in my life... I am going to fight for the values that made me join Labour when I was 18."
When asked if she believed Labour was still, as she claimed, the party of "those who believe in equality", she said: "On a bad day I think 'what on earth is this?' On a good day, I think Labour has been around for 120 years, I've been a member for 56 years. Corbyn hasn't been there for four yet. So that the heart of the Labour Party I joined must still be there... But at the moment we are antisemitic."
She said Mr Corbyn was "not showing zero tolerance" to Jew-hate, as the party has vowed to do.
She also accused him of "allowing... enabling" antisemitism through his personal failure to distinguish between Jewishness, Zionism and support for the Netanyahu government.
"He can't distinguish between someone being Jewish, which I am, somebody believing in the right of the Jews to have self-determination in their own land, which I do, and somebody being a paid up member of the Netanyahu fan club, which I'm not. For him, the three go together."
