One hundred MPs have joined forces to demand compensation for WASPI women ahead of a crucial update from ministers promised next month.

The letter, signed by 100 MPs across 10 different parties, calls on the Work and Pensions Secretary to “reach the right decision” and to set out plans to compensate affected women as quickly as possible.

The signatories say 1950s-born women have “suffered a clear injustice” after being denied the opportunity make alternative plans for their retirement.

Senior Labour and Conservative figures joined forces with dozens of Liberal Democrat MPs as part of the fresh demands, alongside the DUP, Greens and the SNP.

Together, they argue ministers should review the case again, as they did with Winter Fuel Payments, Personal Independence Payments and inheritance tax relief on agricultural properties.

Just days before Government lawyers were set to be hauled before the High Court in December, ministers agreed to reconsider all evidence relating to the case in full, and to do so by Monday 2 March.

Campaigners have hailed a groundswell of support both in Parliament and across the country in recent days, ahead of the crucial update from ministers.

WASPI says more than 50,000 people have written to their MPs so far in support of compensation in just two weeks, highlighting the strength of feeling on the issue.

This equates to one letter being sent every 30 seconds.

Last week, Kemi Badenoch used her weekly appearance at Prime Minister’s Questions to blast Keir Starmer over his U-turn in support for WASPI women. Lib Dem leader Sir Ed Davey has also criticised Labour’s stance, calling for affected women to be compensated.

Angela Madden, Chair of Women Against State Pension Inequality (WASPI), said:

“It’s high time that ministers stopped stalling and started compensating WASPI women.

“The strength of support across the country is palpable, evidenced by one letter being sent every 30 seconds by people from all walks of life to their MPs.

“We have been overwhelmed by growing levels of support in Parliament too. The next few weeks are crucial for Labour ministers to demonstrate they hear the voices of their backbenchers and hundreds across Parliament loud and clear.”

Steve Darling MP, Liberal Democrat Work and Pensions Spokesperson and MP for Torbay, said:

“The Government cannot keep kicking this injustice into the long grass. WASPI women did everything right, yet they were denied proper notice and the chance to plan for their retirement.

“The Parliamentary Ombudsman has been clear, the public are clear, and now MPs from across the political spectrum are clear: compensation must happen.

“Ministers need to stop hiding behind reviews and start delivering justice for the 1950s-born women who have waited far too long for fairness.
