Britain's second-largest construction firm, Carillion, boasted hundreds of government contracts and employed 45,000 people. When it imploded, weeks after the accounts were endorsed by KPMG, the firm left liabilities of almost £7bn – the biggest trade insolvency in UK history. After paying-out hundreds of millions of pounds in ever-rising shareholder dividends, the company's directors walked away enriched – leaving half-built hospitals, roads and other vital infrastructure, a record pension deficit and subcontractors owed over a billion pounds who have never been paid.
