Sir Keir Starmer’s controversial welfare reform bill passed its first hurdle in the House of Commons after it was approved by 335 to 260 votes.
A number of Labour MPs have voiced their concerns over the legislation in recent weeks and dozens voted against it on Tuesday night.
In total, 44 Labour MPs supported a reasoned amendment which proposed to scrap the Government's plans to overhaul the system.
However, a Government defeat was averted after disability minister Sir Stephen Timms offered a further concession during the Commons debate.
York Central Labour MP Rachael Maskell's amendment proposed to decline to give the Universal Credit and Personal Independence Payment Bill a second reading, meaning it would have killed the Bill.
MPs voted 149 to 328, majority 179 to reject Ms Maskell's amendment.

Here is a full list of the Labour rebels who voted in favour of the amendment:
London MPs: Diane Abbott (Hackney North and Stoke Newington), Stella Creasy (Walthamstow), Clive Efford (Eltham and Chislehurst), Margaret Mullane (Dagenham and Rainham), and Bell Ribeiro-Addy (Clapham and Brixton Hill)
Other London MPs: John McDonnell (Hayes and Harlington), Apsana Begum (Poplar and Limehouse), both suspended from the Parliamentary Labour Party for voting against the two-child benefit cap, former Labour leader Jeremy Corbyn (Islington North)

A previous effort to kill the Bill had attracted the support of more than 120 Labour MPs, but was dropped after the first partial U-turn on the legislation last week, which restricted the Pip changes to new claimants from November 2026.
