Purely because the corrupt Stockport LibDems had to prove to a diversion of footpath inquiry that the land wasn’t contaminated, they finally were forced to do something like proper contamination investigations – which they should have done in the first place. This confirmed that the entire site was contaminated with lead, arsenic and brown asbestos. Bent LibDems.
It was the same ghastly firm who carried out the second lot of investigations – no longer called GMGU but now called Urban Vision.
