Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, what proportion of women affected by changes in the state pension age have made an official complaint to the Independent Case Examiner's Office.

We have interpreted this as a question about the number of women who have made a complaint as part of the Women Against State Pension Inequality (WASPI) campaign. All women born after 6th April 1950 have been affected by the changes in State Pension age. There are estimated to be 3.58 million women affected by the State Pension age changes born between 6 April 1950 and 5 April 1960 in Great Britain. 3,521 WASPI complaints have been received by the Independent Case Examiner’s Office, therefore around 0.1% of women in the above birth cohort have made an official complaint to the Independent Case Examiner's Office.
