MADRID — A Spanish mayor who became a hero for staging robberies at supermarkets and giving stolen groceries to the poor sets off this week on a three-week march that could embarrass the government and energise anti-austerity campaigners. Juan Manuel Sanchez Gordillo, regional lawmaker and mayor of the town of Marinaleda — population 2,645 — in the southern region of Andalusia, said food stolen last week in the robberies went to families hit hardest by Spain's economic crisis. Seven people have been arrested for participating in the two raids, in which labor unionists, cheered on by supporters, piled food into supermarket carts and walked out without paying while Sanchez Gordillo, 59, stood outside. He has political immunity as an elected member of Andalusia's regional parliament, but says he would be happy to renounce it and be arrested himself. “You can't be Robin Hood and the Sheriff of Nottingham,” said Alfonso Alonso, spokesman for the ruling People's Party (PP) in the national Parliament. “This man is just searching for publicity at the cost of everyone else.”— Reuters
