Uber goes to court on Monday to overturn a decision stripping it of its licence in London after being ruled unfit to run a taxi service in its most important European market.
Regulator Transport for London (TfL) shocked the Silicon Valley firm last September by refusing to renew its licence, citing failings in its approach to reporting serious criminal offenses and to background checks on drivers.
Uber, whose backers include Goldman Sachs and BlackRock and which is valued at over $70 billion, has faced protests, bans and restrictions around the world as it challenges traditional operators and angers some unions.
