London mayor Sadiq Khan's inquiry into the rocketing costs of converting the London Stadium for West Ham will expose the full retractable-seating fiasco at the centre of the financial crisis.
Contractors Alto Seating, who went into administration last year, somehow convinced the London Legacy Development Company that the annual cost of moving their temporary seats in and out would be just £300,000, compared to the £8million now estimated by companies pitching for the work.
The massive increase is the result of a chronic lack of planning when the stadium was built.
No provision was made for storing the machinery or structure that provides the base for the retractable seats — unlike at Paris's Stade de France, where temporary seats slide in effortlessly on wheels and airbeds.
