Jeremy Corbyn’s allies are planning to end the parliamentary careers of dozens of critical Labour MPs by approving plans for mandatory reselection by the end of the year.

The Telegraph understands his supporters will use their increased majority on the party’s ruling body to clarify rules about which MPs can stand for election after the 2018 boundary review.

Rhea Wolfon, elected to the Labour’s National Executive Committee [NEC] this week, hinted at the move by saying the party must have a “conversation” about “mandatory reselection”.

However Andy Burnham, Labour’s new mayoral candidate for Greater Manchester, said it would “pull the rug from under our MPs” and fuel a “climate of distrust”.
