The controversy within the Labour Party has rumbled on for at least two years.
It shows no signs of abating. What needed to be dealt with root and branch has been the subject of hedging by the Labour leadership.
Over the summer, various pieces of damning information were uncovered by journalists. Labour leader Jeremy Corbyn came under fire for his presence in Tunis in 2014 at what appeared to be an event honouring the terrorists who killed 11 Israeli Olympic team members in 1972. In 2013 he made derogatory comments about British people who favour Israel. He had to apologise for hosting an event in 2010 which included a comparison of Israel to the Nazis.
