Yesterday, John Prescott overruled a planning inspector's report to back Squire's designs for a massive retail and residential development at West End Green, close to London's Edgware Road.
Prescott ignored a rival scheme, designed by Chetwood Associates for Sainsbury's supermarkets, which, if successful, would have scuppered Squire's plans for one of London's most hotly contested retail locations.
In deciding between a number of options for the site, the secretary of state opted for a scheme which incorporated a 22-storey tower instead of 26-storey skyscraper.
Westminster Council, Transport for London and Sainsbury's have all expressed concern over an appeal by developer West End Green Properties - Squire's client.
The developer had lodged an appeal against Westminster council's failure to make a planning decision on the site's future within the statutory period. This appeal was subsequently considered by the Planning Inspectorate.
Sainsbury's now has 42 days in which to start a High Court challenge against the decision.
