Since November 2007 each of HMRC's Business Units has appointed a data guardian to strengthen the management of the Department's data assets. 37 have been appointed in all.
The data guardians are appointed on a functional basis covering all areas of HMRC's business and offices throughout the UK. Data guardians are not appointed by reference to a particular geographical area, but it happens that 24 are based in London, two in Tyne and Wear and 11 in other locations.
