It's the 12th year of this thing, would you believe.

Many of us spend the night before Xmas in the homes of family or friends. But sometimes there isn't much room at the inn. This results in a range of unusual sleeping arrangements. People tweet the photos at me, or tag them with #duvetknowitschristmas, or both. I retweet the highlights. That's it!

If you can spare a donation to Centrepoint, that would be lovely. They help to provide housing and support for the thousands of young people who are homeless this Christmas.
