Davos is hosting the annual gathering of the "great and good" in the world of finance, more commonly known as the "World Economic Forum" (WEF).
It seems that all and sundry are worried about David Cameron's promise of an "in/out" referendum on Europe post the 2015 election if the Tories win.
They should not worry, this is political posturing designed to put UKIP's nose out of joint and to buy Cameron more time wrt his EU discussions.
There is absolutely no guarantee that the Tories will win the next election, nor that Cameron will be leading them; hence the "promise" of a referendum is a meaningless as the oft repeated assurances emanating from Eurozone finance minsters that the "crisis" is over.
