If the U.K. wants a commercial access treaty to the European market, the British must contribute to the European budget like the Norwegians and the Swiss do. If London doesn't want that, then it must be a total exit.

I want France to become the European hub for R&D.

There is no access to the market without budgetary contributions... and without respect for the four freedoms of the E.U.

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.

If I was British, I would vote resolutely 'remain' because it's in the U.K.'s interest.

To avoid the trap of Europe fragmenting on the economy, security, and identity, we have to return to the original promises of the European project: peace, prosperity and freedom. We should have a real, adult, democratic debate about the Europe we want.
