Spain's Prime Minister Mariano Rajoy attends a session of the Upper House of Parliament in Madrid on October 27, 2017. Spanish Prime Minister Mariano Rajoy asked the Senate for the go-ahead to depose Catalan leader Carles Puigdemont and his executive in a bid to stop their independence drive. The central government has invoked the never-before-used article 155 of the Constitution, designed to rein in rebel regions, as it seeks to end Catalonia's drive to break from Spain.

People wave 'Esteladas' (pro-independence Catalan flags) as they gather during a pro-independence demonstration, on September 11, 2017 in Barcelona during the National Day of Catalonia, the "Diada." Hundreds of thousands of Catalans were expected to rally to demand their region break away from Spain, in a show of strength three weeks ahead of a secession referendum banned by Madrid. The protest coincides with Catalonia's national day, the "Diada," which commemorates the fall of Barcelona in the War of the Spanish Succession in 1714 and the region's subsequent loss of institutions and freedoms. / AFP PHOTO / PAU BARRENA (Photo credit should read PAU BARRENA/AFP/Getty Images)
