Which is better: north, south, east or west London? As you might have seen, we're hoping to settle the question with a University Challenge-style quiz event at the Museum of London on 5 July.
Want to be on one of the four teams? You have until the end of tomorrow (Monday) to apply. Simply email firstname.lastname@example.org with subject line "Londoner Challenge North" (or whichever quadrant you want to represent), and tell us why your quarter of the city is best. We'll then pick our favourite responses and get back to the successful candidates on Tuesday/Wednesday.
With 300 questions about London and plenty of good-natured rivalry, the event should be a hoot to watch. You can snap up an audience ticket here for just £6.
