Sir Ian Blair is the latest to step back from the Cash for Honours inquiry into whether the Labour Party gave people Lordships in return for donations and loans.
He follows the Director of Public Prosecutions and hopefully the Attorney General, who is fudging how big a role he will play.
But as more and more people drop out of the game, the question is who is going to conduct this inquiry? Just about anyone appointed by the government has a potential conflict of interest, leaving only police officers below the level of Chief Constable and some low-ranking civil servants.
You have to wonder if the government – and inadvertantly, a critical media – is playing up people’s conflicts of interest in order to reduce the size of the inquiry to one man and his dog?
