More than four million Britons have become the victims of ID fraud, according to new research.

In a poll of 1,000 UK residents, Sainsbury's Bank found that 9 per cent claimed to have had their identity stolen at some point. The average cost per person was £3,039, and some claimed to have lost more than £10,000.

The research highlighted a lax approach to personal information. One in three people surveyed admitted to throwing out old bank statements without shredding them, while one in ten don't bother to tear up credit and debit card receipts.
