Director-General of the National Crime Agency
The Director-General of the National Crime Agency is the head of the National Crime Agency in the United Kingdom, and as such is responsible for the overall management of the NCA. The director is appointed by, and reports to, the Home Secretary, but is not directly part of the Home Office. The director is appointed on a five-year term basis, though this can be renewed (for another five-year term) or extended (for any period less than five years) at the Home Secretary's discretion. As the director is in charge  of a national agency with jurisdiction and investigative powers across the entire country, this post is considered to be the most senior police role in the United Kingdom, outranking the Commissioner of Police of the Metropolis, as the director has the power to direct any chief constables and commissioners. The director is supported by three deputy directors-general, in charge of Operations, Capabilities, and Economic Crime. The current and interim director-general is Graeme Biggar, who was appointed on an interim basis following the medical retirement of Lynne Owens.
