London Mayor Sir Sadiq Khan said: “I want to thank Dame Lynne Owens for her decades of public service in senior roles in the Met, Surrey Police and National Crime Agency.
Dame Lynne joined the police service as a constable in the Met in 1989, later becoming the first female chief constable of Surrey Police.
Commissioner Sir Mark Rowley said:“Dame Lynne Owens is one of the most talented and dedicated police officers of her generation.
She said: “It has been an honour and privilege to return to the Met to support (Commissioner) Sir Mark (Rowley) in making the changes that were needed, and which crucially were wanted by our officers and staff.
Dame Lynne has achieved so much in public life, particularly as director-general of the National Crime Agency and as Chief Constable of Surrey.
