I have just been listening to Bill Cash on Sky. His defence is that he let his son Sam have his Pimlico flat rent free while he then rented out his daughter's flat for £15k. He says that in 2004 it was permissible to do that as the rules allowed it. The rules changed in 2005. He says the "taxpayer was not disadvantaged". Hmmm. Don't think that's going to stick. Essentially, it boils down to the fact that he claimed money for his daughter's flat because he let his son have his Pimlico flat rent free.
Mr Cash has said that he will pay the money back if it is judged he has transgressed. A week ago, that would have probably been sufficient. I wonder if that's the media and public mood now.
