Britain on the Fiddle

It's a national disgrace - £20 billion stolen from the state in 2012 by fraudsters. Richard Bilton pursues a con man who claimed £32,000 in benefits whilst living the high life in Spain and the English Riviera.

A cigarette smuggler thinks he should be knighted for his services to the country but instead he's being pursued for the money he made by dodging duty on tobacco. In Croydon, council investigators try to establish the identity of a woman they have under arrest. Three passports, three National Insurance numbers and over £20,000 are found at her home address. Plus in Hillingdon, the council attempts to keep pace with 'double dippers' - EU passport holders who claim benefits in the UK while living and working abroad.

The case against a multiple-identity fraudster is in danger of collapsing as she tries every trick in the book to avoid her day in court. In Durham, an ex-serviceman who was injured in the line of duty tries to defend his honour as his disability claim is investigated. And in Stoke-on-Trent, an investigator takes on his biggest case yet - a former property developer who is now milking the benefits system by using a second identity.

A mother claiming she works for low pay in a betting shop is caught out in an undercover surveillance operation.
