Jean-Claude Juncker, the European Commission president, says there is no reason to wait until David Cameron is replaced in October to begin negotiating Britain's exit from the European Union.

Speaking to Germany's ARD television station, Mr Juncker added that he wants to start negotiating the UK's reformed relationship with Europe "immediately".

It comes as the EU's six founding members - Germany, France, Luxembourg, the Netherlands, Italy and Belgium - are meeting in Berlin today to discuss Europe's future without Britain.

Meanwhile, senior EU officials have warned that the trading bloc would not be held "hostage" as the Tories conducted a leadership race, with Boris Johnson regarded the front-runner.
