On 3 June 2003 Lassalle stood up in the National Assembly during questions to Minister of the Interior Nicolas Sarkozy and sang the Occitan anthem Se Canta in protest at an announcement by Sarkozy concerning the housing of 23 gendarmes tasked with guarding the Somport tunnel, which links France with Spain through the Pyrenees. The village closest to the French end of the tunnel is Urdos, but it was announced that the gendarmes would be housed in the nearby town of Oloron-Sainte-Marie, on the grounds that their wives would become bored in Urdos.
