I first knew Jenny Tonge when she was a Liberal councillor in Kew, and I liked and respected her.
In part the pariah status she came to occupy for a younger generation of Liberal Democrat activists was precisely because of the generation gap.
When I was a student, anyone with any claim to being on the left was instinctively sympathetic to the Palestinian cause. Nowadays young Liberal Democrats display little influence in it.
But Jenny has also been the author of her troubles, notably in 2010 when she called for an investigation into claims that Israeli forces sent to help in Haiti after the earthquake had been harvesting body parts to send back to Israel for transplant. Surely that was vicious nonsense?
She finally resigned from the party last week after a video of her chairing an event in parliament.
In the words of Guido Fawkes, she did not
interject when an audience member claims Jews 'antagonised Hitler' and that the Holocaust was caused by 'Judea declaring war on Germany'.We've all sat in meetings and stared at the ceiling, waiting for the nutter to finish. But, yes, Jenny should have protested and she should have been more careful about the company she kept.
But if Jenny was right to resign - and I fear she was - then what do we make of the video above. It shows Jerermy Corbyn playing at being a TV host on Press TV, the propaganda channel funded by the Iranian regime.
Note than when the caller appears to be saying something positive about the US, Corbyn pulls him up short. But when he calls Israel a disease, his only reply is "OK".
If Jenny Tonge was right to resign, then so should Jeremy Corbyn.
And you can be sure that the Conservatives are studying his Press TV appearance in readiness for the next election campaign.
