David Cameron touched on the European question during his speech at the World Economic Forum in Davos, insisting that his EU policy was "not about turning our backs on Europe - quite the opposite".
This is about how we make the case for a more competitive, more open and more flexible Europe and how we secure the UK's place in it.
Setting out his case for reform of the EU, Mr Cameron added:
It is not just right for the United Kingdom, it is necessary for Europe. Europe is being out-competed, out-invested, out-innovated and it is time we made the EU an engine for growth, not a cause of cost for businesses and complaint for its citizens.
