Spain’s prime minister, Pedro Sánchez, would be doing the right thing by pardoning the organisers of 2017’s illegal referendum

Madrid’s Plaza de Colón is home to the largest Spanish flag in the world, making it a natural focal point for demonstrations of rightwing patriotic fervour, particularly on matters related to Catalonia. On Sunday, it was packed again. Thousands of protesters made their feelings clear following reports that Spain’s socialist prime minister, Pedro Sánchez, is about to pardon the 12 Catalan politicians who were convicted over their roles in the illegal independence referendum of 2017.

The imprisonment of leading separatists such as Oriol Junqueras, the president of the Republican Left of Catalonia party (ERC), was a draconian response to an episode of foolhardy brinkmanship by the pro-independence movement. The jail sentences handed out to Mr Junqueras and eight other separatist leaders two years ago ranged from nine to 13 years. But a majority of Spaniards are in no mood for showing clemency. The Plaza de Colón demonstration may have been attended by Spain’s three main rightwing parties, but a recent poll found that fully 61% of respondents, and 53% of socialist voters, opposed the idea of pardons. Fewer than 30% were in favour. The failure of the jailed politicians to express any regret for their actions has hardened public opinion and was not lost on the judges of the Spanish supreme court, which has stated that issuing pardons would be “unacceptable”.
