London Assembly Members are to quiz Met Commissioner Sir Bernard Hogan-Howe.about claims in the Guardian newspaper that officers tried to discredit the family of Stephen Lawrence.
Assembly Members previously questioned Sir Bernard over the use of undercover officers and their supervision last September.
On Thursday he will appear before the Assembly Police and Crime Committee and will be asked about the latest allegations of improper behaviour.
The Met has already set up an investigation into the behaviour of undercover officers, including claims that they used the names of dead children to provide false identities.
However Committee Chair Joanne McCartney AM said the latest allegations could not wait for the outcome of that inquiry and “must be dealt with swiftly and openly.”
Assembly Member McCartney added: “Commissioner Hogan-Howe cannot allow these allegations to fester in the long grass, further undermining public confidence in London’s police service.
“It is time for Scotland Yard to come clean about past undercover operations and provide clear assurances that current operations are being properly targeted and carefully supervised for the sake of both the public and the officers deployed in these often very dangerous roles.”
The Police and Crime Committee meeting is at 10am on Thursday 27 June in the Chamber at City Hall (The Queen’s Walk, SE1 2AA).
