Impact of Brexit on UK real GDP - 88% of biggest poll of economist see negative impact on GDP

Just 5% of 700 economists think Brexit would lead to higher GDP, 88% think it would be negative over the next five years, and 72% think it would be negative over the next 10-20 years.  Not the kind of risk that most working people in the UK can gamble with.  Let's not sleepwalk into a DIY recession.
