Donald Trump classifies Britain’s decision to leave the European Union as a revolt against the unchecked immigration into the West, as Thursday’s vote emboldened both the billionaire’s anti-establishment bid for president and various other break-away efforts across Europe.

From the Netherlands to France, political parties opposed to high immigration levels were demanding their own referendums on E.U. membership in the wake of the decision.

“We should have a referendum about a ‘Nexit’ as soon as possible,” Dutch politician Geert Wilders told Reuters, in reference to a proposed Netherlands exit.

France’s right-wing National Front party leader Marine Le Pen made a similar retort on Twitter, while circulating a petition for France to vote on following the U.K. out the European Union door.
