A leaked trove of confidential files has revealed the inside story of how the tech giant Uber flouted laws, duped police, exploited violence against drivers and secretly lobbied governments during its aggressive global expansion.

The unprecedented leak to the Guardian of more than 124,000 documents - known as the Uber files - lays bare the ethically questionable practices that fuelled the company's transformation into one of Silicon Valley's most famous exports.

The leak spans a five-year period when Uber was run by its co-founder Travis Kalanick, who tried to force the cab-hailing service into cities around the world, even if that meant breaching laws and taxi regulations.
