The brother of Stephen Lawrence, who was killed in a racially motivated attack in 1993, has said the Metropolitan Police commissioner's resignation was "needed".
He hoped that Dame Cressida Dick quitting the top job yesterday has set the police "on a pathway now of seeing real change".
Speaking to BBC Breakfast, Stuart Lawrence said: "I have met her a good couple of times and those meetings always have been productive, she has always come across to me personally as someone who wants to implement change and wants to see things done differently, but she just hasn't been able to really put that down to the rest of the forces and the people who are responsible for the different teams throughout the Metropolitan Police force.
