The Women Against State Pension Inequality (WASPI) campaign advocates for women born in the 1950s who experienced changes to their state pension age. These changes, aimed at equalizing the pension age with men, were implemented without adequate notice, leading to financial hardship for many women. WASPI is now pursuing legal action. - WASPI campaigners have sent a 'letter before action' to the Department for Work and Pensions (DWP), signaling their intent to pursue High Court proceedings. - The legal action is prompted by the government's decision to rule out paying compensation to women affected by the state pension age changes. - WASPI accuses both the government and the Labour party of 'gaslighting' the women affected by the pension changes. - WASPI has reached a £75,000 target to help launch the legal battle for compensation.
