Jean-Marie Le Pen [AFP]Anand Naidoo sits in for Riz Khan this week.On Thursday we speak to controversial French politician Jean-Marie Le Pen. Mr Le Pen's party, the National Front, came in fourth in the recent French elections. In the 2002 elections, he had come in second. His positions have alienated much of France's population, with his call to stop immigration (mostly Arab and Muslim), ban the construction of mosques, revive the franc (alongside the euro) and fortify trade barriers.
