Has Front National leader Marine Le Pen really detoxified the party founded by her father 40 years ago? Is it a right-wing protest movement or a party seriously preparing for power? Anand Menon, professor of European politics at Kings College London, analyses the process the French call Dédiabolisation. Le Pen has banished the name of the party and even her own surname from election posters and leaflets. Her party is making inroads into socialist and communist fiefdoms in northern and eastern France. Combining nationalism with a message designed to reach out to the left, she speaks up loudly for the have-nots, people who live in the land she calls "the forgotten France." She targets trade unionists, teachers and gay voters. But widening the party's appeal leads to a tricky balancing act. Can Marine Le Pen manage the process of political exorcism without alienating die-hard supporters? Producer: Lucy Ash.
