Spain the Struggle Continues has protestors vote to occupy Puerta del Sol for another week

Protesters have vowed to stay at least another week in Madrid's central square.

The demonstrators agreed in a show-of-hands vote at a meeting in Puerta del Sol square to stay at least until May 29, when they planned another vote over the future of their makeshift camp.

"We have decided to stay at least until Sunday," a protest organiser declared after the vote.

The protesters remained in the square even as voters cast ballots in local elections Sunday, defying Spain's election commission which has ruled the gathering illegal.

Political protests are banned in Spain on the eve of elections and the day of the vote.

Protesters, who describe themselves as the "indignant", began gathering May 15 in a swelling movement known variously as "M-15", "Spanish Revolution" and "Real Democracy Now".
