Davos, Switzerland (CNN) -- While Prime Minister David Cameron's speech this week -- voicing his intent to let the British people vote on whether to stay in the European Union -- has caused concern on the continent, the mayor of London says it's all part of democracy. "I think if you ask most international business leaders, bankers whether they wanted to abolish elections to remove any element of uncertainty in the commercial world, well of course they would love to do that," Mayor Boris Johnson told CNN's Richard Quest at the World Economic Forum in the Swiss ski resort of Davos, which he described as the "cyclotron of egos."
