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.
