  Ms Le Pen hailed the UK vote, placing a union jack flag on her Twitter page and tweeting: "Victory for freedom. As I've been saying for years, we must now have the same referendum in France and other EU countries."

  The EU worries Brexit could reverse 70 years of European integration.
  In all my years watching European politics, I have never seen such a widespread sense of Euroscepticism.

  Across Europe leading Eurosceptic politicians queued up this morning to crow about the UK referendum result.
  But the mood in Brussels is deeply gloomy. The Brexit vote sends screaming alarm bells, warning that the EU in its current form isn't working.
  Last Friday, Ms Le Pen had told a gathering of far-right parties in Vienna: "France has possibly 1,000 more reasons to want to leave the EU than the English."

  European Parliament President Martin Schulz denied Brexit would trigger a domino effect, saying the EU was "well-prepared".
  But Beatrix von Storch, of Germany's Eurosceptic AfD party, praising "Independence Day for Great Britain", demanded that Mr Schulz and European Commission head Jean-Claude Juncker resign.
  "The European Union has failed as a political union," she said.
