- Prince Harry and Elton John both made appearances at a London court Monday as their privacy case began.
- Lawyers for the royal and other big names told the court the publisher of the Daily Mail commissioned the breaking and entry into private property, illegally intercepted voicemail messages and obtained medical records.
- Associated Newspapers has described the allegations as "preposterous smears" and a "pre-planned and orchestrated attempt to drag the Mail titles into the phone-hacking scandal".
- Britain's phone-hacking scandal saw journalists at the Rupert Murdoch-owned News of the World hack into the voicemails of royals, celebrities and murder victims.
Prince Harry and pop superstar Elton John appeared at a London court Monday, delivering a high-profile jolt to a privacy claim launched by celebrities and other figures against a newspaper publisher.
The publisher of the Daily Mail, Associated Newspapers (ANL), is trying to end the high court claims brought over alleged unlawful activity at its titles.
Harry, who now lives in California, announced in early 2020 he was quitting royal duties and has since launched a barrage of criticism of the British royal family.
Others taking part in the legal action include actor Elizabeth Hurley, John's husband David Furnish and campaigner Doreen Lawrence - the mother of Stephen Lawrence, whose racially motivated murder in 1993 led to the uncovering of serious UK police failings.
Lawyers for the group told the court the publisher of the Daily Mail commissioned the breaking and entry into private property, illegally intercepted voicemail messages and obtained medical records.
"The claimants each claim that in different ways they were the victim of numerous unlawful acts carried out by the defendant, or by those acting on the instructions of its newspapers, The Daily Mail and The Mail On Sunday," lawyer David Sherborne said in written submissions to the court.
The alleged unlawful activities featured "illegally intercepting voicemail messages, listening into live landline calls, obtaining private information, such as itemised phone bills or medical records, by deception", he noted.
Other accusations included "using private investigators to commit these unlawful information gathering acts on their behalf and even commissioning the breaking and entry into private property", Sherborne said.
The alleged wrongdoing dates from 1993-2011, but some went on as late as 2018, he added.
Harry, also known as the Duke of Sussex, sat near the back of the court, two seats away from fellow complainant Frost.
ANL has described the allegations as "preposterous smears" and a "pre-planned and orchestrated attempt to drag the Mail titles into the phone-hacking scandal".
A spokesperson for the firm added they were "unsubstantiated and highly defamatory claims, based on no credible evidence".
Britain's phone-hacking scandal, which first blew up in 2006, saw journalists at the Rupert Murdoch-owned News of the World hack into the voicemails of royals, celebrities and murder victims.
It triggered the closure of the mass-selling Sunday tabloid, a mammoth police investigation, a judge-led inquiry and criminal charges that gripped Britain for years.
A four-day preliminary hearing is being held at the high court with ANL arguing that the allegations are "stale" and should be dismissed without a trial.
Harry, the younger son of Britain's King Charles III, has long had a difficult relationship with the media.
His mother Princess Diana died in a car crash in Paris in 1997 after she and her companion, Dodi Fayed, left the Ritz Hotel pursued by paparazzi photographers.
In 2019 while on a tour of South Africa with his wife Meghan, Harry linked media intrusion to Diana's death and spoke of his fears of history repeating itself.
"I will not be bullied into playing a game that killed my mum," he told television journalist Tom Bradby, accusing sections of the media of waging a "ruthless campaign" against Meghan.
Both Harry and Meghan have been involved in other recent legal action targeting British newspapers.
The couple, whose popularity ratings have plummeted, have dominated headlines in the past few years due to a string of interviews, a Netflix series and Harry's autobiography Spare in which they speak of their treatment as working members of the royal family.
Buckingham Palace has not responded to the claims, while the late Queen Elizabeth II famously commented that "recollections may vary".
John waved to reporters as he was seen leaving the court at the end of Monday's proceedings.
The hearing will resume on Tuesday.
