A retired senior Scotland Yard police officer has admitted authorising secret recordings of a meeting between a friend of murdered teenager Stephen Lawrence, his lawyers and detectives.
Police officers had wanted "an unassailable record of what transpired" in meetings in 1999 and 2000, ex-deputy assistant commissioner John Grieve said.
Mr Grieve, who was director of the racial and violent crimes task force between 1998 and 2002, told the BBC he deeply regretted any distress, dismay or alarm that his decision may have caused Brooks, or Mr Lawrence's parents Doreen and Neville.
Mr Grieve said that at the time his team were both trying to solve Stephen Lawrence's murder and lead the Metropolitan Police response to charges of institutional racism after the Stephen Lawrence Inquiry report.
He denied that officers had sought to trick or deceive anyone involved in the meetings.
