Baroness Louise Casey of Blackstock is to lead an independent review into the Metropolitan’s culture and standards.
The appointment comes after the murder of Sarah Everard by a serving police officer.
Wayne Couzens, 49, was jailed for life last month for her kidnap, rape, and murder.
He will never be released.
The review will investigate the leadership of the force.
Also, how officers are recruited, vetted, and trained.
Metropolitan Commissioner, Dame Cressida Dick, said:
“The appointment of Baroness Casey to lead the independent review in to our culture and standards is an important step in our journey to rebuild public trust.
“Louise is extremely experienced and highly respected and I know will ask the difficult questions needed for this thorough review.
“This will build a stronger Met, ensure lasting improvement our service to London and public confidence in us.”
The force has already started an inquiry into all allegations of sexual and domestic abuse against officers and staff.
Ms Everard, 33, was abducted her as she walked home in South London in March.
Couzens used his position as a police officer to stop her, handcuff her and put her into his car.
He told her she’d broken lockdown curfew rules.
Baroness Casey said: “Trust is given to the police by our, the public’s, consent.
“So, any acts that undermine that trust must be examined and fundamentally changed.
“This will no doubt be a difficult task, but we owe it to the victims and families this has affected and the countless decent police officers this has brought into disrepute.”
