Spain protests: 'This has never happened before'

Some 25,000 Spanish protesters have defied a government ban and camped out overnight in a square in the capital, Madrid.

The protesters object to the government's economic policies and have occupied the area for the past week.

Spain's electoral commission had ordered them to leave ahead of local elections on Sunday.

The BBC's Sarah Rainsford in Madrid said that the demonstration was continuing well into Saturday and that such a spontaneous display of protest was unlike anything seen in Spain before.
