Top Tories including Boris Johnson and Dominic Raab are at risk of losing their seats from a voter revolt against Universal Credit cuts, Labour claimed tonight.

The Prime Minister and Foreign Secretary are among 118 Conservative MPs whose majorities are smaller than the number of local welfare claimants set to be stripped of £20-a-week, according to Labour research.

The Government is resisting mounting pleas to make permanent the temporary hike in the benefit – worth £1,040-a-year to six million of the poorest families.

Hard-up households are due to be robbed of the rise after September – despite warnings from campaigners it will plunge them into poverty.

Labour says 9,677 claimants will be clobbered in the PM's Uxbridge and South Ruislip constituency in West London – 2,467 more than his 7,210 majority.

In Mr Raab's Esher and Walton seat in Surrey, 5,520 claimants could be hit – 2,777 more than his 2,743 majority.

Shadow Work and Pensions Secretary Jonathan Reynolds has written to Cabinet Minister Thérèse Coffey urging her to abandon the autumn UC cut.

His letter, seen by the Mirror, warns her: “You will know that there is now near-universal opposition to these plans.

“Labour, the public, the House of Commons, dozens of charities and campaign groups and now your six predecessors as Conservative Work and Pensions Secretaries of State all agree that this money must remain in place.

“Families across the UK have spent the past year worried for their jobs and their family’s financial security.

“If the Government pushes ahead with this cut, it would be devastating for millions already struggling to get by, leave unemployment support at a 30-year low in the midst of a jobs crisis and threaten our economic recovery.

“After everything the country has been through the Government could give millions of families the certainty they need today by doing the right thing.

“For the families relying on this money, for our economy and in the national interest, I implore you to cancel this cut.”

A Government spokesman said: “Universal Credit is continuing to deliver during the pandemic, providing a vital safety net for six million people, and the uplift was part of an extensive £400billion package of measures put in place that will last well beyond the end of the roadmap.

“The six-month extension to the uplift was a temporary measure to support households affected by the economic shock of Covid-19.

“Our focus now is on our multi-billion pound Plan for Jobs, which will support people in the long-term by helping them increase their hours or find new work.”
