“For Macron it is a power grab. He wants to centralize the EU in the EU’s central institutions (…) Angela Merkel wants a(n) EU that works for Germany and for the german business community – it exports an aweful lot to Britain. So she wants Britain locked into the EU’s customs union.” Alexander Mercouris, The Duran, 6.4.2019
It’s a difference of tactics (between Macron and Merkel), not so much a difference of strategy.
Each one wants a more centralized EU. Macron wants a more supranational EU, controlled from Brussels, Merkel wants a german dominated EU, controlled from Frankfurt and Berlin.
Macron wants the British out, because they will impede his project of a centralized, supranational EU, whereas Merkel wants the British in, because they are a(n) important market for german business. That’s it in a nutshell.”
