Princess Beatrice has had her protection officers reinstated for public events whenever she is representing the Royal Family, Express.co.uk has learned.

According to a source, the Home Office’s Royal and VIP Executive Committee (RAVEC) takes on the task of protecting lower-level members of the Royal Family, those not assigned personal protection officers, whenever they are at publicised events, and it is known they will be in attendance.

“Whenever Beatrice attends large-scale public events where it is known she will be attending, security will be provided by RAVEC,” said the source.

“She will also be in touch with someone from the RAVEC department at all times [whether] she is at an event or not, just in case something were to happen while she was out and about.

“There’s an emergency number for members of the Royal Family to reach out on and there is also some kind of locator positioned on their person in case they get lost.”

The source adds that Beatrice’s personal protection officer, also known as a PPO, will not be reinstated on a full-time basis. The protection move will only come into effect for public events.

In 2011, both Princess Beatrice, 35, and Princess Eugenie, 34, lost their taxpayer-funded police protection in a move that is said to have left their father Prince Andrew extremely worried for their safety.

On the official Home Office website, RAVEC describes its work as the body that “exercises executive authority for national policy for protection of royalty and VIPs”.

It was also the department that took over Prince Harry’s protection efforts during his visit to London for the Invictus Games 10th-anniversary service at St Paul’s Cathedral in May.

“RAVEC looked after Harry in May and also made sure that all members of the Royal Family are safe whether they are working royals or not,” said the source.

“Any public event has extra security efforts involved and there will always be someone on hand to guide the royal through the day prior to their attendance. A mini security briefing as it were.”

A Home Office spokesperson said: “The UK Government’s protective security system is rigorous and proportionate. Providing detailed information on those arrangements could compromise their integrity and affect individuals’ security.”

Buckingham Palace declined to comment.
