They say they're selling it rather than just closing it which means it may take a while before it actually closes. As I understand it, Wetherspoons only has a leasehold interest so they'll have to find someone to sell it to and once that's done, they'll have to get the freeholder's consent to sell the lease to that particular purchaser. The freeholde in turn may need to get their mortgagee's consent (if the building is subject to a mortgage). the freeholder (and the mortgagee) will need to be satisfied that the purchaser has the financial strength to pay the rent etc etc and then the lawyers will get involved - these things all take time so unless all of that is already in progress, it could be a while yet before they close their doors.
