Angry, pop star Elton John denounced in British court on Friday the "odious" attacks on his privacy committed, according to him, by the tabloid Daily Mail, mentioning in particular "hacking" of his telephone lines.

The performer of "Your Song" and "Rocket Man" is one of seven plaintiffs, along with her husband David Furnish and Prince Harry, who have filed a lawsuit against Associated Newspapers Ltd (ANL), owner of the Daily Mail and the Mail on Sunday.

They accuse these tabloids of having illegally obtained private information, which ANL denies.

In front of the High Court in London, where Elton John appeared via video link for a little over half an hour, the pop legend did not hide his anger.

Dressed in a green suit jacket and a blue shirt, he argued that this trial was about "the most odious things in the world that one can suffer from a privacy standpoint".

The 78-year-old singer is referring to articles published between 2000 and 2015.

"We have three landlines and they were all hacked, including the junction box at the end of our street," the star recounted. This made him "furious," he added, believing that he and his husband had "suffered an injustice."

He also said he did not grasp the "seriousness of the facts" at the time the articles were published.

- "Abject" -

In his written testimony, a copy of which was obtained by journalists, Elton John also referred to the "abject intrusion" of these tabloids into his health affairs and at the time of the birth of his first son, Zachary.

On Thursday, during his testimony before the Court, David Furnish referred to the publication in December 2010 of their son's birth certificate.

David Furnish had also mentioned a detailed article published in 2015 about medical problems Elton John had in Monaco.

ANL's lawyers, for their part, argued in their written submissions that the information published by the tabloids came from relatives of the personalities who initiated this legal action.

"Their friends, as well as friends of their friends or associates, regularly provided information to the press about the plaintiffs' private lives (...) in a confidential manner," the lawyers stated.

They also claimed that Elton John's spokesperson "regularly provided the media, including ANL journalists, with information" about the couple's life, including medical information.

The spokesperson in question "no longer works for us," Elton John told the court. "My friends don't talk to the press, and that's why they remain my friends," he also stated.

"For people who live in the public eye, it is essential to have safe spaces where privacy is respected," he also stressed in his written testimony.

Prince Harry, who lives in California, testified in court on January 21. Visibly moved, he accused the tabloids of making his wife Meghan's life "hellish".

The following day, Elizabeth Hurley tearfully accused the newspapers of having placed microphones on the windows of her house.

The ANL group rejects the accusations against it and asserts that the tabloids used "legitimate" sources for their articles.

The trial opened on January 19th and is expected to last nine weeks.
