'I promised to expose the corruption' - Daniel Morgan's brother

The Home Office is to announce an independent review into the murder of private investigator Daniel Morgan in south London in 1987.

Six criminal investigations have failed to identify who killed him with an axe.

It has been alleged police corruption prevented the Metropolitan Police from solving his murder.

Daniel's brother Alastair, who has campaigned through five police investigations and a collapsed trial for someone to be held accountable, tells BBC's Newsnight programme "I made a promise to expose the corruption."
