Met chief Dame Cressida Dick left the job last week, with her deputy Sir Stephen House temporarily taking the reins until a permanent successor is appointed in the summer.
The outgoing Commissioner demanded operational independence from local and central government for the Met in a year when the Mayor of London ousted her.
The embattled Police Commissioner, 61, will step down for good on April 10 after a string of recent scandals within the Metropolitan Police forced her to quit the top police role.
Sir Tom Winsor, HM chief inspector of constabulary, praised the majority of officers but said that some who have a fondness of violence and of abusing their power need to be rooted out.
