Although the British Transport Police is not under the control of the Home Office, and as such was not included as part of the proposed mergers of the Home Office forces of England and Wales in early 2006, both the then London mayor Ken Livingstone and then head of the Metropolitan Police Sir Ian Blair stated publicly that they wanted a single police force in Greater London. As part of this, they wished to have the functions of the BTP within Greater London absorbed by the Metropolitan Police. However, following a review of the BTP by the Department for Transport, no changes to the form and function of the force were implemented, and any proposed merger did not happen.
