Madrid (CNN) -- Chanting "they don't represent us," tens of thousands in Madrid railed early Sunday against Spain's government and austerity cuts -- venting their anger on the first anniversary of the so-called May 15 protest movement. The government earlier had given a 10 p.m. (4 p.m. ET) Saturday deadline for the crowd in the central Puerta del Sol plaza to disperse. Yet while their numbers appeared to thin somewhat by early Sunday, they remained a loud and vibrant presence in the square -- as a large number of police, stationed at a nearby government building and along side streets, looked on and let them be.
