Women Against State Pension Inequality (Waspi) campaigners have questioned the ongoing delays and "disgraceful behaviour" used by the Government to decide the compensation they are owed.
The women affected are waiting for payouts of between £1,000 and £2,950.
During Monday's Department for Work and Pensions (DWP) oral questions, Secretary Liz Kendall faced repeated inquiries about the timeline for addressing the issue.
Ministers consistently refused to provide a specific schedule for responding to the Parliamentary and Health Service Ombudsman's (PHSO) report on state pension age changes stating they were still considering the findings.
The Ombudsman report established that the DWP did not properly inform the Waspi generation women of the state pension age change from 60 - 65. The group published a report in March saying the women should get payouts of between £1,000 and £2,950.
Labour's inaction on compensating Waspi has come under scrutiny as the Government marks 100 days in power this.
Pressure is building on ministers to bring forward proposals for compensation, ahead of the Autumn Budget which is set to take place on October 30.
Waspi women have already been hit financially due to historic changes to the state pension GETTY Waspi campaigners have questioned the ongoing delays, pointing out that the Parliamentary Ombudsman's report is shorter than Labour's election manifesto.
This lack of progress has frustrated campaigners and affected women alike as over 11,000 Waspi women passing away without seeing compensation. Many are accusing ministers of continuing the previous administration's "can-kicking" approach.
Hundreds of women have reacted furiously on social media to the lack of progress on the issue.
Tania Wickham said: “So they criticised the last government for not compensating the women swiftly enough, one assumes they had already read the report thoroughly at that stage. Yet more delaying tactics-disgraceful behaviour.”
Jean Symons shared this view adding: “It's already been 'looked at' by the ombudsman. Now Labour you need to stop looking and start doing. Too much prevarication!”
More than 11,000 Waspi women have died since Labour’s landslide election win on July 4. Since then, more than 300 MPs have pledged their support for the campaign – many of them newly elected.
An early day motion calling for a debate on a "proper plan" for compensation has gained support from 90 MPs across the political spectrum.
This cross-party backing includes members from the Liberal Democrats, SDLP, Plaid Cymru, and the Green Party, as well as Labour, SNP, and Conservative representatives.
Waspi campaigners are planning to amplify their demands with a protest outside Parliament on October 30, Budget Day.
Commons leader Lucy Powell acknowledged the significance of the Ombudsman's report, stating: "The Ombudsman has established that the DWP did not properly inform the WASPI generation women of the change." She added that the Government is taking time to review the report due to its complexity.
Angela Madden, Chair of Waspi, highlighted the campaign's concerns: "The Government campaigned on the grounds of being the party of social justice and of getting things done, yet as Labour marks 100 days in power, their lack of progress means ministers risk continuing the can-kicking of the Conservatives."
Liberal Democrat Spokesperson for Work and Pensions, Steve Darling MP, added his voice to the calls for action: "Ministers must quickly step up for 1950s-born women and implement the findings of the Parliamentary Ombudsman's report without delay."
Many groups are arguing for the Government to grant compensation of at least £10,000 each to the affected Waspi womenGETTYThe Waspi campaign stems from changes to the state pension age for women born in the 1950s, increasing it from 60 to 65. In March, the PHSO report found significant "maladministration" by the DWP in communicating these changes.
The report recommended compensation ranging from £1,000 to £2,950 for affected women, noting they lost at least 28 months of preparation time.
However, Waspi campaigners are advocating for higher compensation of over £10,000.
The debate over appropriate compensation continues, with former Work and Pensions Committee chair Sir Stephen Timms.
He said: "The debate over the impact of the DWP's failure to communicate increases in the women's state pension age has dragged on for too long and it is time the Government took action to resolve the issue."
