The part leaking to the press of the Government’s EU Exit Analysis – Cross Whitehall Briefing’[i] highlighted the dire consequences for many parts of the UK of leaving the EU in the June 2016 referendum. The leak and its handling also exposed the extreme reluctance of the Government to provide the information necessary for informed public debate. The Government asked the civil service to investigate three scenarios: Remain in the single market; A free trade deal with the EU; No deal. The public have been denied the opportunity of properly assessing for themselves these three outcomes, since no details have become available about the assumptions, methodology or data used in arriving at the impacts on GDP summarised in Table 1 (below).
In the light of the above we would draw attention to the study of the regional and sectoral impact of Brexit, commissioned by the Federal Trust and undertaken by Dr Andrew Black (Senior Fellow at the Global Policy Institute). This study considers four scenarios which cover tariff impacts, the impacts of lower investment and consumption for each sector, and their related multiplier effects. The assumptions behind the results are made clear as are the data sources and the input-output methodology.
The lack of details for the Government study makes comparison difficult. However, Dr Black’s study shows some marked divergences from what we know of the government study. His study shows:
- rather less variation between regions under all scenarios, so even the South-East is hit hard
- rather worse outcomes for 7 of the 12 regions, while Wales, the East of England and the North East do better in the government study
- far worse outcomes across the board in the worst case scenario; also different rankings (Table 2).
