Bradford & Bingley, admitted yesterday that it had been forced to take an £18 million impairment charge in the half year to June 30 to cover borrowing by criminal gangs and other fraudsters. The sum represents an increase on a £15 million charge taken in June. B&B’s losses may be only the tip of the iceberg. The Association of Chief Police Officers has estimated the scale of mortgage fraud in the UK at £700 million a year, but many believe this to be conservative. Navigant, a consultancy that conducts forensic investigations, has estimated that British mortgage lenders could be sitting on at least £7 billion of fraudulent loans. B&B, which has 3 per cent of the mortgage market, is the first high street bank to disclose the size of its losses due to fraud. Rod Kent, its chairman, said that the bank had not been singled out and was no more vulnerable than other lenders. “We don’t think we are being selected, we are just being more transparent,” he said.
