BRASILIA, July 13 (Reuters) - Brazil will reduce the federal tax on diesel from 0.31 reais ($0.06) to 0.27 reais, President Jair Bolsonaro said on Tuesday, adding that Economy Minister Paulo Guedes was on board with the measure. Diesel prices are a sensitive topic in Brazil, where truckers’ strikes can paralyze large sectors of the economy.
