I'm going to spend a Saturday night in September sleeping on the streets of central London, and not just because I have lost my keys/wallet/dignity. A group of us, including my mum, are doing a Big Street Sleep in aid of Calcutta Rescue, a charity which raises funds for the disadvantaged in West Bengal. (You can find out more about the  at www.calcuttarescue.org.uk)

It would be most kind if you could spare a few pennies for this extremely worthwhile cause. In exchange I will tell you where we are sleeping so you can point and laugh at me. Thank you x
