"I'm thrilled to be joining DCMS. It's a small department but with a big reach - at the heart of all those quality of life issues that bring fulfilment, excitement and interest to millions.
"And it helps to sponsor some of the biggest industries in Britain, from tourism, to communications, to fashion. All that, and the 2012 Games too. I can't wait to start."
