European Commission chief Jean-Claude Juncker said Tuesday that a British exit from the EU was not an option, saying there was "no plan B" as Prime Minister David Cameron held key talks in Brussels to avert a "Brexit".
Cameron, who wants the EU to carry out controversial reforms before he holds a referendum on Britain's membership, held talks with European Parliament chief Martin Schulz to drum up support for his proposals, AFP reports.
Schulz said there were "concerns to raise" as Cameron arrived, pledging that the parliament would be an "honest partner" in the talks.
