Tom Watson MP: Phone hacking claims 'will shock parents'

An investigator working for the News of the World allegedly hacked into the mobile phone of murdered girl Milly Dowler, a lawyer for the family says.

Mark Lewis said police told her parents that Glenn Mulcaire hacked into her voicemail while she was missing.

A News International spokesman said it had been co-operating fully with the police inquiry into hacking since News International's "voluntary disclosure in January restarted the investigation into illegal voicemail interception".

He said: "This particular case is clearly a development of great concern and we will be conducting our own inquiries as a result. "We will obviously co-operate fully with any police request on this should we be asked."

Speaking to the BBC, Labour MP Tom Watson said he was shocked by the allegations.
