Andrew Windsor in therapy due to fear of house arrest

Photos taken near Marsh Farm show extensive new security features installed around the property. A six-foot fence has been installed behind an existing wooden barrier, while additional fencing has been installed along the side of the farm.

CCTV cameras and powerful outdoor lighting have also been installed, and airspace restrictions over the estate have reportedly been tightened.

A notice at the property warns visitors not to approach and states that journalists and photographers are prohibited from entering the grounds of the Sandringham estate.

An insider said such measures are intended to prevent break-ins and keep Windsor’s movements largely invisible.

Another royal source said the king’s advisers see the arrangement as a necessary step to protect the monarchy from further reputational damage.

They added: “There is a clear attempt to draw a line between the monarch’s constitutional role and the personal problems facing Andrew Windsor. The view within the palace is that the institution should not be defined by its legal problems.”

Sources familiar with the renovation work say Marsh Farm had been vacant for some time before plans were made for Windsor’s move.

A source involved in the project said: “The building required substantial renovation regardless of who would eventually live there, but the extent of security measures has become much more extensive due to Andrew Windsor’s situation.”
