Earlier the same day, the semi-autonomous region's former vice president and leader of the Republican Left of Catalonia party, Oriol Junqueras, was given the longest prison sentence of 13 years. Also, judge Pablo Llanera, who was heading the investigation case, reissued an international arrest warrant for Carles Puigdemont, former Catalan president who now lives in exile in Belgium.
Catalonia has been striving to secede from Spain for decades. On 1 October 2017, Catalonia held a referendum in which 90 percent of those who voted supported the region’s independence from Spain. The turnout was, however, less than 50 percent. Madrid declared the referendum illegal and arrested a number of pro-independence leaders.
