Good Cause of the Day

Precinct Theatre has been supporting its local community in Islington for 10 years, with drama workshops, dance classes and performances particularly for children and young people from the local estate. But its venue is being demolished and they need help moving from their current location in Packington Square N1 to near Old Street today and tomorrow. If you can help with packing or shifting, just turn up at Units 2/3 Packington Square between 10am-7pm today and from 9am on Saturday. And if you feel like donating to help them find a new space, there's an Indiegogo appeal.

London Connection Puzzle

Your complete set of clues, then, is 38, 24, 11 and 9. What's the London connection? Lots of people have worked it out, so no need to email in. The solution will be revealed on Monday.

From the Archive

On this day last year, we learnt which London institution has the world's longest Facebook timeline, and previewed a 'human butchery' opening in Smithfield.

London Weather by Inclement Attlee

Today's forecast is brought to you via the medium of mime. Unfortunately, it doesn't translate very well into the electronic format, so you'll have to physically track me down to see the outlook. I'll be here all day, though, miming away to anyone who passes.

Would you like to forecast the Londonist weather? I’ll be away for the start of next week, so we’ll need accurate and in-no-way-silly forecasts for London on Monday and Tuesday. Fancy having a go? Rather than typing out some words, you should draw, paint, or photograph your forecast (or perhaps craft it from leftover vegetables or Lego bricks) and send it to hello@londonist.com (subject line: ‘Attlee’s minion’).
