Reacting to Le Pen's refusal to appear on France's TF1 television channel on Tuesday unless the EU's yellow-starred blue flag was removed, the Commission tweeted: "Proud of our flag, a symbol of unity, solidarity and harmony between the people of Europe". She wants an in-out referendum on France's European Union membership, a new French franc to replace the common euro currency, and to reimpose French borders to staunch what she describes as out-of-control immigration.
