As Anand Menon (from UK in a Changing Britain), points out, for the European Union:
'An economically flourishing post-Brexit UK risks inspiring Eurosceptics elsewhere. As one senior German official put it... recently, “we have no interest in making Brexit work”.'
Herein lies the UK's problem: rebuilding trade relations with the EU is more important to the UK than it is to the EU, which has other things to consider.
Escaping the consequences of Brexit is not easy!
