A senior journalist on Britain's biggest-selling newspaper the News of the Worldwas jailed today for bugging the mobile telephones of members of the royal family's household.
The Sunday newspaper's royal affairs editor Clive Goodman listened to voicemail messages left for the press secretary of heir-to-the-throne Prince Charles and also for two officials who worked for his sons, princes William and Harry.
Goodman (49) was jailed for four months and his accomplice, private investigator Glenn Mulcaire (36) was given a six-month prison term.
After the two were sentenced, News of the Worldeditor Andy Coulson resigned, saying he took "ultimate responsibility."
"His actions were entirely wrong and I deeply regret that they happened on my watch," he said in a statement.
"When the News of the Worldcalls those in public life to account on behalf of its readers, it must have its own house in order," he added.
Phone were tapped "several hundred" times in a bid to obtain exclusive stories.
Goodman and Mulcaire admitted last November to plotting to unlawfully intercept communications while Mulcaire also pleaded guilty to five other charges of unlawfully intercepting voicemail messages.
London's Old Bailey court heard the duo had begun a "relatively sophisticated" scheme to bug Prince Charles's Clarence House residence in London in December 2005.
They also tapped the phones of Australian supermodel Elle McPherson, a member of parliament and the head of England's Professional Footballers' Association, the court heard.
"This was low conduct, reprehensible in the extreme," said Mr Justice Gross.
"This case is not about press freedom. It is about grave, inexcusable and illegal invasion of privacy. The targets were members of the royal family. The royal family holds a unique position in the life of this country. It is grave indeed."
Paul Horrocks, President of the Society of Editors, condemned the offence afterwards and said: "We do not believe that it is a widespread practice."
The scam was uncovered after minor stories appearing about the princes aroused suspicion in the royal household and staff became concerned their phones were being monitored.
The paper suspended Goodman after he was charged last August and he apologised to Prince Charles and his sons for a "gross invasion of privacy".
Snooping on the royals has been a rich source of scoops for the scandal-hungry tabloids.
In the early 1990s, their pages were plastered with transcripts of the "Squidgygate" and "Camillagate" tapes - recordings of Charles and his then-wife Diana talking intimately to their lovers on the telephone.
Earlier this month, Prince William called on the media to stop pursuing his girlfriend, Kate Middleton, after photographers and film crews camped outside her house as rumours grew that the couple would announce their engagement.
