Amendment intended to kill off legislation that would cut benefits could be backed by up to 100 Labour MPs including senior figures

Labour MPs have launched a significant rebellion against the government’s ​benefit cuts with an amendment that could kill its ​welfare bill, spearheaded by senior select committee chairs.

The amendment – which has been signed by 108 MPs – declines to pass the government’s welfare changes and calls for a pause, including for further consultation and for support to be in place before any further cuts are made.

The Guardian understands the amendment has been led by the Treasury select committee chair, Meg Hillier, and a number of other committee chairs. It has also been signed by former cabinet minister Louise Haigh and Vicky Foxcroft, who quit as a Labour whip last week.

They claim the amendment, to be published on Tuesday, is not intended to wreck the welfare bill but as many Labour MPs are uneasy about the government’s plans that could be the eventual outcome.
