If the UK leaves the EU, what will happen to the UK economy? In this video, Anatole Kaletsky argues that Brexit would be economic suicide, or at least self-harm.

This video was recorded during the “Economics of the UK’s EU Membership” conference organised by the National Institute of Economic and Social Research in February 2016 and held in London.
