Starmer Faces Mounting Labour Rebellion After Housing Bill Defeat and Deepening Polling Slump

Prime Minister Keir Starmer is under intensifying pressure from within his own party after the UK government suffered its first Commons defeat on June 10, 2026, when the flagship housing bill was rejected by 12 votes. The defeat underscored eroding party discipline and fueled calls among Labour MPs for a change in leadership.

A YouGov tracker published June 18, based on a survey of 2,000 UK adults conducted June 15-16, placed Starmer's net favourability at minus 45, matching an Ipsos poll from the same period. The polling slide follows Labour's loss of more than 200 seats in the May 2026 local elections.

At least 30 Labour MPs have publicly called for Starmer's resignation, though no formal leadership challenge has been launched. Internal party rules require a threshold of MP nominations to trigger a contest, a figure not disclosed in public statements.

Starmer has not indicated any intention to step down. The government has not announced plans to reintroduce the defeated housing bill, leaving one of its core legislative priorities in limbo.

The next test for Starmer's leadership will come in any upcoming by-elections and in the Labour Party conference scheduled for later this year, where internal dissent could become more visible.
