Removing all trade and tariff barriers as part of a hard Brexit would generate ‘a £135 billion annual boost to the UK economy’, according to Professor Patrick Minford on behalf of Economists for Free Trade — while those who claim his ideas spell economic suicide are ‘hired hands, they work for government, they work for big industry…’ Well maybe, as I frequently say: Minford talks of a 4 per cent GDP gain from free trade, 2 per cent from ‘improved regulation’ and more from reclaiming our net EU budget contribution and ‘removing the taxpayer subsidy to unskilled immigration’.
