French Jews holding dual Israeli citizenship will have to give up one of their nationalities if Marine Le Pen, the far-Right candidate, wins the presidential election this spring.

The leader of the anti-immigration Front National said she would bar French nationals from holding the citizenship of countries outside the European Union, except for Russia, which she described as part of “the Europe of nations.”

An admirer of Vladimir Putin, Ms Le Pen said dual US nationals would also have to forgo their American citizenship, despite her support for Donald Trump and her enthusiastic backing of his executive order restricting travel to the United States from seven mainly Muslim nations.
