One of the demonstrators camped in a central Madrid square to protest the economic crisis has won €1.3m in the national lottery, Spanish lottery officials confirmed today.

'The prize of €1.3m has been attributed this weekend. We tried in vain to get in touch with the winner all day on Sunday,' said Ignacio Garcia, the head of Serviapuestas, the website of the Spanish lottery.

'We were finally able to speak to him today and he told us that he was in the encampment in the Puerta del Sol, so that is why he had not been able to reply by telephone or check his emails,' Mr Garcia said.

The winner is a 34-year-old man from Madrid.

Protests over the economic crisis and soaring unemployment began in Madrid on 15 May and fanned out to city squares nationwide as word spread by Twitter and Facebook among demonstrators also known as 'M-15', 'Spanish Revolution' and 'Real Democracy Now'.

Protesters installed in Madrid's Puerta del Sol square dismantled their camp on Sunday.
