Scotland Yard detectives are today re-examining whether a series of celebrities and other high-profile individuals - including former Deputy Prime Minister John Prescott - were victims of phone hacking after fresh evidence emerged.
According to today's Daily Mail up to 3,000 potential targets of phone-hacking by private investigator Glenn Mulcaire are to be contacted.
The Mail reported that up to 20 people, told after the original 2005 invesitigation into voicemail hacking at the News of the World there was little or no information about them, are now believed to have been targeted.
The Mail reports sources saying that a hardcore of 100 phone-hack targets are expected to be discovered.
Among the names arising in the new evidence are former deputy prime minister John Prescott who is among several potential phone-hack targets currently bringing a judicial review claim over Met Police handling of the matter.
Scotland Yard has stressed that at this time there is no evidence to suggest that voicemails were actually hacked.
