The UK votes on whether to leave or remain in the European Union on 23rd June. What is the financial case for each side? Roger Bootle is executive chairman of Capital Economics, author of The Trouble with Europe and a member of an eight-strong group of independent economists, Economists for Brexit. He predicts an exit from the EU would increase the UK's output and competitiveness. Thomas Sampson is from the London School Of Economics and has recently authored a paper called, Economists for Brexit: A Critique. He says Britain would be stronger by remaining in the EU.
