Given its congested roads and polluted air, some may argue that London is a sick city. It is also the most populated and ethnically diverse city in the EU. Public health experts are facing difficult dilemmas in deciding what the priority should be for public health in London.

As part of the Story of London festival, we're holding a balloon debate, and you get to decide which public health project flies and which ones get ditched.
