We have to be extremely strict on the implementation of Brexit so there is a common approach between member states. We must avoid a sector-by-sector or country-by-country approach, and ask the U.K. to be clear.

I am attached to a strict approach to Brexit: I respect the British vote, but the worst thing would be a sort of weak E.U. vis-a-vis the British.

Sovereignty is not just at the national level; that's the mistake of Brexit that other people make.

Brexit is the other face of the refugee crisis - tensions that lead to stasis, external risks that lead to asymmetric shocks.

Our interests lie in attracting added value and talent to France as a result of Brexit, but also in having a balanced relationship with Great Britain. We must not sacrifice the short term for our bilateral relationship.

As to the euro zone avant-garde, it must go towards more solidarity and integration: a common budget, a common borrowing capability, and fiscal convergence.
