Question to the Cabinet Office:

To ask His Majesty's Government, further to the Written Answer by Baroness Anderson of Stoke-on-Trent on 6 March (HL5301), (1) on what date the data on senior civil servants who registered for One Big Thing 2023 was deleted, (2) whether any data was retained beyond the stated 12-month period, and (3) how the Evaluating One Big Thing 2023 report, published on 30 January, included detailed registration figures by department if the data had been deleted before that point.

Data collected via the One Big Thing 2023 online platform was deleted by 31 December 2024, in line with the platform’s privacy statement. Beyond 31 December 2024, we retained aggregated data on overall registrations and % registrations by department.

The analysis reported in the Evaluating One Big Thing 2023 report was completed before the data was deleted but publication was delayed due to various factors including the General Election.
