PARIS (Reuters) - The French far-right Rassemblement National (RN) of Marine Le Pen kicked off the party's campaign for the European elections in June on Sunday saying the vote will be a referendum on immigration.

Opinion polls show RN is set to make large gains in the elections - some polls crediting it with 28%-30% support - and that it could pose a major challenge to France's mainstream parties, including President Emmanuel Macron's Renaissance.
