Speaking to people on the left in recent weeks, there is certainly some appetite among Corbynistas to de-select right wing Labour MPs, who it is feared will never by loyal to Jeremy Corbyn as leader. For Corbyn to develop and implement a clear programme, then put it to the electorate in 2020, such people have to go.
But who will they be replaced by? An interesting example of who is waiting in the wings comes from Birmingham, where there are reports the former Respect party leader Salma Yaqoob is being lined up for a Labour seat. The incumbent at Birmingham Hall Green, Roger Godsiff, is having none of it. Although Godsiff fought off Yaqoob when she stood for Respect in 2010, she was a strong second on that occasion. The demographic changes in the constituency since surely suggest that if he were de-selected, and stood against Yaqoob as an independent or for any of the other parties, he would lose. Birmingham Hall Green Constituency Labour Party could have a very big decision to take.
Interestingly this story broke whilst Yaqoob was out of the country, addressing the annual conference of the Australian arm of the Muslim Brotherhood, the Australian Islamic Mission. Among the speakers was a fellow Brit in the shape of Anas al-Tikriti, who runs the Cordoba Foundation, the Muslim Brotherhood's think tank in the UK. Al-Tikriti is a fixture at the Ikhwan's Finsbury Park Mosque, where the MP for Islington North, Jeremy Corbyn holds constituency surgeries.
I am sure that Ms Yaqoob and Dr Al-Tikriti had much to discuss. But not at the Islamic Mission's lunch - that was, of course, segregated.
