British Prime Minister David Cameron will be meeting with senior Cabinet advisers seeking support for a new deal that would govern Britain's relations with the European Union ahead of a U.K. referendum on EU membership that could be held as early as this summer.

Cameron has called the meeting for Saturday morning. He may announce a referendum date afterward.

The deal was reached Friday in Brussels at a summit of the 28-nation bloc's leaders. Cameron said after it was announced that he would campaign "heart and soul" for a "yes" vote in favor of remaining within the EU.

Cameron says he has achieved the concessions he sought from other leaders. Still, he faces skepticism within his own Conservative Party about the merits of retaining Britain's ties with the EU.
