The Metropolitan Police commissioner has said he is "pleased" after meeting with the mother of murdered teenager Stephen Lawrence over claims that undercover officers hunted for information to smear her family.
After the meeting, Sir Bernard Hogan-Howe said: "The Deputy Commissioner and I were very pleased to have the opportunity to meet Doreen and Stuart Lawrence today. It was a constructive meeting.
"These are serious allegations and I understand why the Lawrence family want answers quickly. I am determined for Operation Herne to establish the facts as quickly as possible for an operation of this size".
Doreen Lawrence has said it will "take a while to gain trust" after she met with the Metropolitan Police commissioner over smear claims.
Scotland Yard has been confronted with another accusation of underhand tactics in its investigation of the murder of Stephen Lawrence.
The father of murdered teenager Stephen Lawrence said he felt "betrayed" by allegations the Met Police tried to smear his family.
