Latest firm to be censured for legal tax avoidance is SABMiller, brewers of Grolsch and Peroni beers.

According to Ethical Consumer magazine research from ActionAid showed that the firm avoids millions in tax by shifting profits out of poor countries, such as those in Africa, and into tax havens like Switzerland. If SABMiller paid tax in Africa then ActionAid have calculated that an additional 250,000 African children could get an education.

Students at the University of Edinburgh have boycotted all SABMiller beers.
