Allies of Jeremy Corbyn have allegedly drawn up a list of MPs placing them in either his “core group” of supporters or a “hostile” camp.
The document, which was leaked to the Times, was reportedly complied by the Labour leader's political secretary Katy Clark in January.
Labour Mayoral candidate Sadiq Khan was reportedly placed in the “hostile” camp, along with former Labour leader Ed Miliband.
A spokesman for Jeremy Corbyn's office said that they had no knowledge of the list: “It doesn’t come from this office and we have no knowledge of it.”.
