From the Telegraph:
Locked up and tortured by the dictatorship which ran Brazil during the 1970s, she was once branded by a prosecutor as the "Joan of Arc of subversion".
Yet in less than a month's time Dilma Rousseff is on course to become Brazil's first woman president, entrusted with running the largest and fastest-growing economy in Latin America.
Her first election campaign has gathered the apparently unstoppable force of a steamroller and Ms Rousseff is likely to win the first round of voting outright.
If she pulls it off, it would seem like a miracle for a 62-year-old apparatchik who has never before been elected to any political post and who was unknown to most of Brazil's 192 million people a few months ago - until you look to see who is behind the wheel of the steamroller.
