Which brings me to David Davis and the real reason behind his trip to the US this week. On the face of it Davis is on a fact-finding mission to discuss zero tolerance policing and defence. In reality, he's about to attend the most important job interview he'll ever have. The Shadow Home Secretary will this week face an assessment by the Americans as to his suitability to be Prime Minister. He's being cleared for the top job. If all goes well and Davis gets the nod, at some stage later this year David Cameron will get wind of a draft letter calling for a vote of no confidence in his leadership. At that point he will announce that he is to step down to spend more time with his family.
As Richard Littlejohn might say, you really couldn't make it up. But the UK Daily Pundit has. I haven't had such a good laugh since I almost wet myself at a Frankie Howerd live theatre show.
