The campaign to include a museum in the Trent Park redevelopment has now received royal backing.

The Prince's Regeneration Trust, a group created by the Prince of Wales to adapt and preserve historic buildings, has given support to the Trent Park Museum team.

The group want Berkeley Homes, the new owners of Trent Park, to provide enough space to create a national attraction telling the story of the house’s role in winning World War Two.

Campaign director and founder Jason Charalambous said: "I am delighted the Prince's Trust recognises the importance of saving Trent Park for the public and the nation.

“Berkeley Homes need to recognise the importance of providing sufficient space within their luxury housing development in the middle of our park to enable our team to establish a national museum for the benefit of the local community and beyond.

“What they have currently offered is nowhere near acceptable, however I am looking forward to continued constructive discussions with them in securing the space needed for a viable attraction".

Berkeley Homes are expected to submit a planning application in early September for an extensive luxury development of Trent Park’s buildings and grounds, including current plans for 260 houses and flats.

However, they are currently only offering less than half the ground floor and basement for the desired museum and learning centre, while campaigners want the whole ground floor, basement and half the stable block for the museum.

Other supporters of the museum idea include Iain Standen, chief executive of Bletchley Park, actor Sir David Jason, and Sir Michael Bear, former Lord Mayor of the City of London who is leading the team's advisory board.

During the war, Trent Park was an MI6 “intelligence gathering prison” for the most senior captured German officers, before becoming part of Middlesex University, and was eventually bought by Berkeley Homes.

Over 5000 people have signed a petition calling for the establishment of a museum, and a recent public meeting in Cockfosters attracted over 350 people.
