Prince Harry

A former royal diary editor has told the High Court that Prince Harry's social circle was far from the 'impenetrable fortress' described by his lawyers, and insisted she relied on 'chatty friends' for exclusives.

Katie Nicholl, who led the Mail on Sunday diary desk for nearly a decade, testified on 13 March 2026 that the Duke of Sussex's friends frequently provided information on his private life.

Giving evidence in the high-stakes privacy trial against Associated Newspapers (ANL), Nicholl rejected claims that she commissioned private investigators to hack voicemails, describing the allegations as 'groundless' and 'damaging' to her professional reputation.

The Duke of Sussex, locked in a privacy showdown with Associated Newspapers—the force behind the Daily Mail and Mail on Sunday—heard Nicholl push back hard against claims his pals stayed schtum.​​

This marathon trial kicked off in January, pitting Harry and a roster of big names—Baroness Doreen Lawrence, Sir Elton John, David Furnish, Sadie Frost, Liz Hurley, and Sir Simon Hughes—against the publisher over alleged privacy invasions stretching back two decades. They're accusing ANL of commissioning private eyes to hack voicemails, tap landlines, and blag confidential records for splashy stories, with Harry's beef centred on 14 articles from the noughties and early teens that his team says reek of illegality. ANL flatly denies it, calling the suit a desperate straw-clutch and pointing to legit sources all along.

Prince Harry's Inner Circle Opens Up, Court Hears

Nicholl, who helmed the Mail on Sunday's diary desk from 2004 to 2012 and still freelances for the titles, didn't mince words under cross-examination from ANL's silk, David Sherborne KC. He put it to her that Harry's mates were 'well aware' of press scrutiny and 'very tight-lipped'—a cornerstone of the duke's argument that leaks had to come from foul play. 'They were not all tight-lipped,' she shot back. 'They certainly were not. I had very good sources in the inner circle.'​​

She painted a vivid picture from her early brushes with the young prince, recalling a Kensington Roof Gardens bash around April 2003, when a cig-smoking Harry led her into a private room. 'It's not every day you get invited to a party by one of the most famous princes in the world,' she quipped, shrugging off Sherborne's jibe that she was exaggerating her access. Those contacts, she stressed, were real friends dishing on late-night texts and calls that spiced up her columns, not some shadowy hack job.

Take a 2007 exclusive on Hugh Grant's flirtations with a Warner Bros exec, overheard by Jemima Khan and passed via a trusted freelance stringer; or Harry's godparent gig for Tiggy Legge-Bourke's kid, likely tipped by the late Lady Elizabeth Anson, a Legge-Bourke pal and Queen's confidante. 'It's very difficult to remember what conversations I had in 2001,' Nicholl admitted when pressed, but the family ties spoke for themselves.​

Privacy Battle Unravels on Recanted Claims

What sharpens the irony here is how much of the claimants' case hinges on now-torched evidence from private investigator Gavin Burrows. He once 'admitted' to voicemail busting and blagging for Mail journalists, pocketing tens of thousands from Harry's research outfit—only to recant spectacularly, crying forgery on his 2021 statement and insisting he'd never worked the titles. ANL says there's zero record of him, and Nicholl claims she'd never heard the name. She rubbished phone-hack inferences from her stories' phone chit-chat: 'The suggestion... is nonsense.' Sources showed her the texts, with consent, or spilt on overheard calls—standard diary fodder to prove a fling's heat.​

Nicholl's frustration boiled over in her written evidence, labelling the accusations 'groundless and damaging' to her career. Hugh Grant's 2011 Leveson Inquiry sideswipe got her suspended from ABC News gigs stateside; she cornered him at a 2013 do, protesting her innocence. Now Harry's camp keeps the fire stoked via Byline Investigates, the site run by his legal sleuth Graham Johnson—'very unfair,' she fumed, 'based on absolutely no evidence.'​

ANL's defence has layered on more rebuttals: ex-editor Paul Dacre vaguely recalled £3m in PI invoices but demanded specifics; another gumshoe denied instructions for unlawful grabs. Harry's own witness statement paints his press ties as 'uneasy,' bound by the royals' 'never complain, never explain' mantra—yet here he is, spilling in court.

Nicholl wrapped her testimony, insisting she'd 'never knowingly used illegally obtained information, hacked a phone... or asked anyone to do so.' Whether that sways the judge—or exposes Harry's leaky fortress—remains the billion-pound question in this privacy brawl.

A Legal Showdown Reaching Its Climax

The trial, presided over by Justice Nicklin, is entering its final weeks. ANL continues to argue that the lawsuits are a 'desperate straw-clutch' and that the information was sourced legally through palace officials, freelancers, and public records. Prince Harry's witness statement, however, paints a picture of a life haunted by press intrusion, governed by a royal 'never complain, never explain' mantra that he has now decisively abandoned.

As the proceedings wrap up at the end of March 2026, the judge must determine if the evidence supports a pattern of systemic illegality or if, as Nicholl suggests, the Prince simply had a leakier circle of friends than he realised.
