BB. It's a bit of a belated reply, but here goes ......

You said you "thought wigan boro council purchased said estate for the people of wigan".

Well, is the Moon really made of green cheese?
The 'council' is the government. Everything the council has is really the government's. It's all known as 'government assets'.
Haigh Hall is a government asset. It's managed by Wigan council, but it's an asset of the government, whatever party is in office. In other words, it doesn't belong to Labour.
Now, getting back to the future of Haigh Hall. The government have looked into what's happening to their asset and have taken action. The Cabinet Office have forced the use issue under their Government Estates Strategy, enforced by the Government Property Unit.
Wigan council are merely glove puppets in the great scheme of things!
