The Business: British retail's Christmas bonanza

On this week's Business podcast, Aditya Chakrabortty is joined by Dan Roberts and Deborah Hargreaves to discuss a bumper Christmas period for many of Britain's retail giants. Our confidence may have returned, but is there a downside to our rampant spending? Also in the podcast, Tim Webb answers our questions about the state of Britain's gas supplies . Crisis? What crisis? Finally, we go downtown in Motown and hear from Andrew Clark at the Detroit Motor Show about the health of the US car industry . We'll have a special programme on bankers' bonuses next week, but in the meantime, have a listen, post your comments on the blog below, and subscribe to us on iTunes .
