Sara Thornton has not applied for Met commissioner role
Chief Constable of Thames Valley Police Sara Thornton has not applied for the role of Metropolitan Police commissioner.
On the day of the deadline for applications for Britain's top police job, she issued a statement dismissing speculation about her future.
She said being linked to the job was flattering, but she had not applied.
When it was first advertised last month she was made joint favourite for the role by betting firm Ladbrokes.
In a statement, Ms Thornton, who has been chief constable at Thames Valley Police since 2007, said: "There has been much speculation over the last few weeks about whether I might make an application for the role of the commissioner of the Metropolitan Police Service.
"While it is flattering to be considered suitable for such an important role I have decided not to apply."
Ms Thornton worked at Scotland Yard for 15 years from 1986 before heading to Thames Valley Police, which covers Oxfordshire, Berkshire and Buckinghamshire.
The previous Met Commissioner Sir Paul Stephenson stood down amid the phone-hacking scandal.
The deadline for applications to be his successor passed at midday.
Four policemen are understood to have applied for the job.
