RIO DE JANEIRO — Brazilian President Dilma Rousseff has signed into law a bill giving FIFA the needed guarantees to organize the 2014 World Cup, but one of her vetoes will force soccer's governing body to negotiate the sale of discounted tickets with the states.

Rousseff approved the sale of alcoholic beverages inside stadiums, which was the most contentious issue because sales have been illegal in Brazil. It was a demand by FIFA because Budweiser is a major sponsor.

One of the five vetoes related to making available only 300,000 half-priced tickets for students and the elderly. With the veto Wednesday, discounted tickets can be sold in all ticket categories, so FIFA will have to work with state governments to have their laws altered to avoid it.
