The Government Equalities Office (GEO) is the unit of the British government with responsibility for social equality. The office has lead responsibility for gender equality within the UK government, together with a responsibility to provide advice on all other forms of equality to other UK government departments. The unit is based at the Cabinet Office. Prior to April 2019, the GEO was led concurrently by Cabinet Secretaries at the Home Office, DFID and DfE. The day-to-day responsibility for policy on these issues was not transferred to GEO when it was created. The Equalities Office currently leads the Discrimination Law Review, which developed the Equality Act 2010 that replaced previous anti-discrimination legislation. The current minister responsible for GEO is Kemi Badenoch, who also serves as Secretary of State for Business and Trade in the Rishi Sunak government.
