Wales abuse victims 'must come forward'

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.

David Cameron has ordered an urgent investigation into the handling of claims of child abuse at care homes in North Wales in the 1970s and 80s.

One man, Steve Messham - who says he was abused by a senior Conservative politician of the time - said the inquiry uncovered only a fraction of the abuse.

Councillor Keith Gregory says he was also sexually, physically and mentally abused in a Welsh care home in the 1970s, and that he has a list of alleged abusers who were never fully investigated.
