Prime Minister Tony Blair said Monday that it was too early to say if Britain will hold a referendum on the proposed EU constitution, the British news agency Press Association reported. Foreign Secretary Jack Straw indicated Britain would wait a week to announce its intentions. Blair was speaking to reporters in Tuscany, Italy, a day after France rejected the treaty in a referendum that cast serious doubt on whether the ratification process will continue across Europe. To date, nine countries have approved the text, which needs to be unanimously adopted. Blair, who was expected to call a popular vote on the constitution next year, would face a major battle for a "yes" vote. He said Monday it was now "time for reflection," Press Association reported.
