The mother of murdered teenager Stephen Lawrence will meet the Home Secretary today. Doreen Lawrence is expected to call for either a Leveson-style inquiry or an independent panel to look into claims that undercover police hunted for information to smear her family.
Lawyer, Michael Mansfield QC said: "She will be wanting something done in public, and the nearest example is Leveson, or an alternative scenario is one like the Hillsborough panel that looks at all the material.
"One of these two has got to happen. Not another internal inquiry which will not be made public because they will claim it's sensitive information."
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.
