GMB members have warned Labour’s “unbelievable” decision to keep the two-child benefit cap will make voters switch to the Lib Dems.

A motion condemning the policy, which prevents parents from claiming benefits for more than two children, was passed at the union’s annual conference today.

It noted: “Unbelievably, last year Sir Keir Starmer decided that scrapping the two-child benefit cap would no longer be Labour Party policy, despite the estimations that this would lift around 270,000 households with children out of poverty.”
