Anyone wanting to become a police officer in London will have to have been living in the capital for at least three of the last six years as the force aims to become "more reflective of the city it serves".
Hiring local officers will ensure a good local knowledge and maintain the trust and confidence of residents, Metropolitan Police Commissioner Sir Bernard Hogan-Howe has said.
Sir Hogan-Howe added: "Recruiting constables with a knowledge and understanding of this reality through living in the capital makes sense to help us achieve this aim.
"They will have a better understanding of local issues, knowledge of local communities and an inbuilt insight into London's varied cultures. We need great talent to help us fight crime."
