Cameron Tells Davos That He Can Keep the UK in the EU

European Parliamentary elections are to be held in May

(Reuters) - Prime Minister David Cameron said on Friday he was confident he could renegotiate Britain's relations with the European Union to allow it to remain in the 28-nation bloc.

In some of his most pro-European remarks to date, Cameron told the World Economic Forum in Davos that changes needed to make the euro zone function better meant the EU would need to alter its treaties.

That would give Britain an opportunity to recalibrate its own relations with the EU.
