France is holding first-round regional elections Sunday, where the far-right National Front party is expected to make gains in the first electoral test since the IS attacks on Paris last month, UPI reported. Elections are being held to select representatives for the 13 regions of domestic France and four overseas territories, BBC News reports. The National Front (FN), an anti-immigration and anti-European Union party led by Marine Le Pen, is the third largest political party in France. It has never controlled a French region, but polls indicate an FN lead in several of the country's 13 regions. Le Pen, 47, is expected to win the northern Nord-Pas-de-Calais-Picardie region of France and her 25-year-old niece Marion Marechal-Le Pen may win the southern region of Provence-Alpes-Cote d'Azur. Regions in France have significant say on matters of education, transportation and economic development. Le Pen, who will be a likely contender in France's 2017 presidential election, is the daughter of Jean-Marie Le Pen, founder of the FN.
