I don't know what we can do when this man is taking the role of judge, jury and executioner to himself more and more. If he is found to have taken bribes - and that is surely what they are if he cannot put them on record - will anything happen or will he just choose to stay in his post?
He is being investigated by the Electoral Commission on suspicion of breaking electoral law. If they find him guilty he can be fined a maximum of £20,000 and the EC can, if they think it necessary, pass the papers to the police for a criminal investigation.
If it's just a fine, I think he will ignore the implications and carry on as though nothing has happened. It won't bother his supporters, who regard corruption as normal behaviour, and he isn't bothered about breaking the Ministerial Code or violating the Nolan Principles.
Criminal investigation? It would be interesting to see how that panned out...
