The MPs from across different parties have called on the Work and Pensions Secretary to “reach the right decision” and set out plans to compensate 1950s-born women affected by changes to the state pension urgently.

Those who have signed say women affected have “suffered a clear injustice” after being denied the opportunity make alternative plans for their retirement.

The letter has been signed by senior Labour and Conservative figures alongside dozens of MPs from the LibDems, DUP, Greens and the SNP.

SNP figures who have signed the letter include Pete Wishart, Seamus Logan, Brendan O’Hara and Graham Leadbitter.

Just days before UK Government lawyers were set to be hauled before the High Court in December over the rejection of compensation, ministers agreed to reconsider all evidence relating to the case in full by March 2.

Waspi [Women Against State Pension Inequality] says more than 50,000 people have written to their MPs so far in support of compensation in just two weeks.

Angela Madden, chair of 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.”

On November 11 last year, Work and Pensions Secretary Pat McFadden said his department would review the policy not to compensate women born in the 1950s who were affected by the increase in the pension age.

A report by the Parliamentary and Health Service Ombudsman had previously suggested that compensation ranging between £1000 and £2950 could be appropriate for each of those affected by how state pension changes had been communicated.

In December 2024, the Government had previously said that, while it accepted the ombudsman’s finding of maladministration and apologised for a delay in writing to 1950s-born women, a blanket compensation scheme, which could cost taxpayers up to £10.5 billion, could not be justified.

Recent court proceedings led to the rediscovery of a 2007 Department for Work and Pensions evaluation, which led to officials stopping sending automatic pension forecast letters.

Waspi has argued that a lack of sufficient information led to women planning their finances based on incorrect understandings, which has left them having to work longer or facing financial hardship.

Waspi has said a judicial review that was previously planned will not take place while the Government reconsiders its compensation decision, but it could relaunch the process at a later date.
