Good Cause of the Day

Crimestoppers has just launched a new campaign to catch people who live in luxury off the proceeds of crime. The crime-fighting charity wants to hear from you if you have evidence of a person or business benefiting from illegal activity. The scheme is explained in detail here, including how Crimestoppers works with the police. You can contact Crimestoppers anonymously on 0800 555 111 or through

London Weather by Inclement Attlee

Cloud, mist and fog are the watchwords of the day. Old Granny Attlee once gave me the following tip, which I find useful for navigating through such smogs. First, hook up your vacuum cleaner to a mobile generator. Next, stow it all into a very large rucksack, and sling it over your back. You can now use the hose to suck up any lingering fog as you walk along the street. The captured vapour can even be recycled. Simply sell the swollen vacuum bag to a gig promoter, who can turn its contents into a cost-effective 'dry ice' stage effect at a later date. As a secondary bonus, people might think you're a Ghostbuster.

Want to provide the forecast? I'm going on a short holiday at the end of the week. This will mean no forecasts for a couple of days. So to fill in, I'm going to hand the reins over to any reader who wants to have a go at meteorological prediction. There's a catch — you can't just write the forecast down. You must draw, sculpt, photograph or otherwise create something to represent the London skies. We need forecasts for both Monday and Tuesday next week. So please send any entries ASAP to, with subject line 'Attlee's minion'. No bodily fluids.
