Sketch: Cameron hits the road all at sea Exciting transport news. The Coalition, said David Cameron, "has a full tank of gas," is going "full steam ahead," and is "on the right track." The Prime Minister unveiled this remarkable invention in an interview with Andrew Marr on BBC One. The Christmas break seemed to have done Mr Cameron good. Having looked worn and sallow towards the end of 2012, his face had regained its old Plasticine smoothness. He also had some new clothes: normally he favours white shirt and dark blue tie, but yesterday he was modelling a light blue shirt and purple tie. They went beautifully with the view of London from the studio window, the shirt reflecting the light blue of the sky, the tie reflecting the purple wisps of early-morning cloud. Marr asked mainly about the EU, and the inequities of the child benefit cut. As a result of this cut, a family with £80,000 a year will retain full child benefit (provided the parents earn, say, £40,000 each), whereas a family with £60,000 (one parent earning all of it, the other staying at home) will get no child benefit. Mr Cameron didn't explain how this was fair. He might at least have suggested that if both parents are working, they need child benefit more, what with the cost of childcare. But he didn't. Marr moved on to the Prime Minister's fabled speech on Europe. How can we be sure the thing exists? And if it does exist, and is released to the public, can it hope to live up to expectations, after all these years of hype? And, most importantly, the question that excites fans of Cameron and Salinger alike: will it represent a thrilling change of direction - or will it just be more of the same? Yesterday the Prime Minister shed a little light by saying that he'd finally be giving the speech "in mid-January."
