Brazil president Dilma Rousseff has signed the document that will temporarily allow alcohol to be drunk at the 2014 World Cup.

World football's ruling body FIFA had requested a change in the law following an agreement it signed with a major brewery.

The temporary amendment will also be applied to the Confederations Cup, to be held in 2013. It was finally published Wednesday following a long battle with members of parliament and of the Senate, who had approved the text on May 9.

The amendment includes a stipulation that will also be welcomed by students, the elderly and those less well-off.

After FIFA spent many months lobbying Brazil to soften its stance on beer in stadiums, Brazil secured from FIFA guarantees that it could sell a minimum number of match tickets at half-price to students, people aged over 60 and those who normally receive government hand-outs.

FIFA is set to put 300,000 tickets aside for Brazil to sell them on at half their face value.
