The Royal and VIP Executive Committee (Ravec) has carried out a fresh risk assessment and concluded that the Duke of Sussex now meets the criteria for official police protection.
Harry appeared at a two-day court hearing last May, where his legal team argued that his personal safety was at risk without publicly funded security.
The 41-year-old previously lost his legal challenge after Ravec ruled he was no longer entitled to police protection, citing his status as a non-working royal.

Following the initial ruling, Harry was reportedly deeply upset and accused the Royal Household of playing a role in the decision.
In September, the Invictus Games founder wrote to Home Secretary Shabana Mahmood after a stalker managed to get dangerously close to him during a visit to London, according to The Independent.
The individual, who had a history of making online threats, breached a designated “secure zone” while Harry was attending an event for children’s charity WellChild that same month.
Notably, the incident occurred on a day when Harry had been granted police protection.
Two days later, during a visit to Imperial College London, the same stalker allegedly attempted to approach the Duke again but was stopped by a member of Harry’s private security team.
These alarming incidents reportedly led Ravec to reopen and reassess the security risks surrounding the Duke.

Harry has consistently maintained that he and his family — wife Meghan Markle, 44, and their children, Prince Archie, 6, and Princess Lilibet, 4 — cannot safely travel to the UK without official protection, citing persistent online threats and intense media scrutiny.
The Sussexes stepped back from their senior royal roles in January 2020 and are now based in California.
Meanwhile, the couple has faced recent internal changes, including the departure of James Holt, their longest-serving staff member, from their Archewell Foundation.
They also parted ways with their publicist, Meredith Maines, less than a year after she joined their team.
