Calls to close corporate tax holes in UK

A week after the UK's coalition government announced another $15bn worth of cuts to public services, anti-austerity campaigners are focusing on big corporations that many people believe are not paying their fair share of taxes. Some estimates place multinational tax evasion in the UK at up to $40b annually. US-based firms such as Starbucks, McDonald's and Kentucky Fried Chicken are among the latest companies to be cited as paying only a fraction of taxes on billions in annual profits.
