A former undercover police officer has claimed he was ordered to infiltrate the Stephen Lawrence campaign in 1993, the Guardian has reported.
Peter Francis told the newspaper and Channel 4's Dispatches programme he posed as an anti-racism campaigner in a hunt for "disinformation" to use against those criticising the police.
The aim was to smear the dead teenager's family, he said.
Scotland Yard refused to confirm or deny the account.
