the implementation of the Statistics and Registration Service Act 2007, the role of Registrar-General for England and Wales, an ancient additional title, held by the National Statistician since the inception of ONS, was transferred, with the General Register Office for England and Wales, which she also headed, to the Identification and Passport Service in the Home Office Controversy A government policy inherited by Karen Dunnell as National Statistician aroused controversy. Following the efficiency reviews initiated by the Chancellor and Prime Minister (viz. Review of Public Sector Relocation by Sir Michael Lyons, 2003–04, and Releasing Resources to the Front Line, Sir Peter Gershon, 2004), the government adopted a policy, criticised by unions, of dispersal of certain public service posts and functions out of London.

She also cited the benefits to the local economy, the skills of existing ONS staff in Newport and access to universities and other resources in the region as well as the benefits of operating key functions from a
