British Prime Minister Mr Tony Blair readied for a battle in his bid to convince Britons to support the newly agreed European Union constitution in a referendum.
"The reason I am doing this is not because I would like yet another issue for people to kick me around on, but because I believe it is in the interests of Britain," Mr Blair said on BBC's Breakfast with Frostprogramme.
"It will be a tough battle...it is reality versus myth," he said, adding he would not be pushed into holding the vote early.
Mr Blair, who only a week ago suffered heavy losses in European and local elections, has pledged to hold a referendum on the constitution.
A "no" vote in Britain would throw the future of the charter into doubt as it must be ratified by all 25 member nations. It would also probably spell the end of Mr Blair's premiership.
A YouGov poll for the Sunday Times showed voters would reject the constitution by 49 per cent to 23 per cent while an ICM poll for the cross-party Vote No campaign showed 57 per cent opposed it.
Another poll cited by the Observer showed 69 per cent of voters thought the deal gave too much power away over jobs, living standards and asylum policies.
The main opposition Conservative party has the constitution and says it would try to renegotiate it. Its foreign affairs spokesman, Mr Michael Ancram, called the EU constitution a "gateway to a country called Europe."
Blair even faces opposition from within his own Labour party with some dissenting members already talking against the charter.
