Brazil has received a $13.5bn (£7.9bn) boost from staging the World Cup this summer, according to a survey commissioned by the country's Ministry of Tourism.

Despite the host nation making an ignominious exit from the competition after a 7-1 defeat to Germany in the semi-finals, the survey – conducted by the Economic Research Institute Foundation - based its findings on income from last year's Confederations Cup.

The 2013 tournament, won by the Selecao on home turf, was said to have added $4.3bn (£2.5bn) to Brazil's GDP and it is expected that the World Cup will inject treble that amount into the country's coffers.

At the start of the tournament, protesters took to the streets, complaining that staging the tournament had detracted from dealing with Brazil economic problems.

Romario, now a Brazilian parliamentarian, has called for an inquiry into "excessive spending and corruption" linked to the World Cup.
