Britain will be worse off under any Brexit scenario, according to internal report, as pressure mounts on government to release its findings
The January 2018 study examined three of the most plausible Brexit scenarios

The UK government was under pressure on Tuesday to publish its latest Brexit analysis after a leaked internal report said Britain would be worse off whatever deal it strikes with the EU.
The economic impact assessment, drawn up for the Brexit ministry and seen by the BuzzFeed News website, showed growth would be lower under a range of potential scenarios.
The leak came as Prime Minister Theresa May prepared to fly out on a three-day trade mission to China and as parliament’s upper House of Lords began scrutinising the EU (Withdrawal) Bill, a key plank of Brexit legislation.
The January 2018 study, titled “EU Exit Analysis”, examined three of the most plausible Brexit scenarios.
If found that if Britain remained in the European single market, growth would be 2 per cent lower over the next 15 years compared to current forecasts.
The government must now publish their analysis in full, so that MPs and the public can see for themselves the impact that Brexit will have
Under a comprehensive free trade agreement with the European Union, growth would be 5 per cent lower, it said. And if London and Brussels end up with a “no deal” scenario and revert to World Trade Organisation rules, growth would be reduced by 8 per cent over the same period, the report said, according to BuzzFeed News.
