Davos, Switzerland (CNN) -- Free trade, transparency and a crackdown on tax cheats will be at the heart of Britain's G8 presidency, Prime Minister David Cameron told the World Economic Forum in Davos on Thursday as he set out his vision for a more competitive Europe. The speech comes a day after Cameron made headlines by promising the British people a vote on European Union membership if he wins the next general election in 2015. "We need more free trade. We need fairer tax systems. We need more transparency on how governments -- and yes, companies -- operate," Cameron told political and business leaders at Davos.
