Ahead of the February deal, Cameron sought to revise the terms of his country's membership of the bloc, centering on four key issues — shifting power away from EU authorities back to the UK national legislature, exempting Britain from the EU "superstate" principle, stripping the euro as the single official EU currency, and protecting the British economy by keeping eurozone members away from non-eurozone countries’ affairs.
"The British policy-makers and the British voters have to know that there will be no kind of any renegotiation [of the conditions of London's EU membership]. We have concluded the deal with the [UK] Prime Minister [David Cameron], he got the maximum he could receive — we give the maximum we could give. So there will be no kind of renegotiation," Juncker told reporters.
