Inquiry into sexual abuse claims at north Wales homes
Correction 10 November 2012: The BBC has apologised unreservedly for broadcasting a report on Newsnight on 2 November over allegations of child abuse which transpired to have involved a case of mistaken identity. As a result the video of the original report has been removed from the website. More details can be found here.
The prime minister is appointing a "senior independent figure" to look into the way allegations of sexual abuse at north Wales children's homes in the 1970s and 80s were dealt with.
Victim Steve Messham has said that the Waterhouse inquiry of 2000 only covered a fraction of the alleged assaults.
Another of the homes' residents says it did not hear all of the abuse claims.
Earlier, Downing Street said it would investigate Mr Messham's claims of abuse by a 1980s Tory politician.
