Policy Exchange’s Director of Economics and Social Policy Warwick Lightfoot appeared on BBC News to discuss the leaked government analysis of the impact of Brexit over the next 15 years. Lightfoot warned that such reports should be treated sceptically due to the difficulty in making accurate long term economic forecasts, that past analyses of the benefits of EU membership are flawed, and that the UK’s future prosperity will depend on what British governments do with regard to public spending, public borrowing, taxation and openness to international trade.
