Tzipi Livni and Jeremy Corbyn

It is difficult to keep up with all the stories coming out now quoting Jeremy Corbyn on Israel/Palestine issues, but this one caught my eye.  Extraordinarily, it quotes Jermey Corbyn as saying in 2009 that he had never heard of Tzipi Livni before.  As well as being Leader of the Opposition now, at the time of the quote she had been a Cabinet Minister in Israel for the previous eight years, and was serving as Israel's Foreign Minister at the time.  As such she was a key figure in any attempts to create a peace agreement.  How can it be claimed that Jeremy Corbyn was even interested in any peace process if he had never heard of her?
