Allotments are chunks of land set aside for housholds to grow their own fruit and veg. Its generally an older gen (plus some younger woke) that use them, so nobody who the telegraph readers will care about. The councils have had a very hard time of it from the party in power due to many factors, and some are on the verge of bankruptcy. [1]
So being able to sell land that is genrally in walking distance to other residental zones to devlopers would be a welcome shot of cash. With the thin justification of "Its better for the enviroment" to keep most the would be defenders busy arguing if it is, or isnt, untill the deals are done, and they are lost.
It almost funny when the UK also has a general, saying that "Britain must train citizen army" [2], and allotments were promoted so the UK could feed itself when being blockaded. [3]
