British Prime Minister David Cameron said in London that it is uncertain whether there will be a referendum this year on Great Britain's remaining in the European Union (EU), which is demanded by the UKIP opposition party, which advocates leaving the EU.
Cameron promised to negotiate relations between London and Brussels and to organize a referendum by the end of 2017 if he wins the parliamentary elections on May 7 this year.
"We need to start those negotiations (with Brussels) as soon as possible. But I honestly believe that there is little chance of that happening in 2015 after the elections," Cameron told British television ITV.
UKIP leader Nigel Farage said on Sunday he would consider a post-election deal with the ruling Conservative Party if it meant a referendum on EU membership this year.
According to the latest polls, Labor and the Conservatives are equal in strength, even if they cooperate with a third party after the election.
