Stuart Lawrence, the brother of Stephen, has told ITV's This Morning his family's lawyer has put 13 questions to the Met Police Commissioner regarding claims undercover officers hunted for information to smear the Lawrence family.
He says if they are answered a public inquiry would not be needed but says, if they are not, an inquiry would be in the public's interest:
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.
