PARIS, May 9 (AFP) - France remained cut in half over the European Union's proposed constitution, with supporters of the text slightly ahead in new opinion polls released Monday.  

Two polls - one by CSA institute, the other by TNS-Sofres - gave the "yes" camp 51 and 52 percent of the vote respectively in the May 29 referendum, with no change since their previous polls carried out at the end of April.  

But according to an Ipsos poll also released Monday, the supporters of the treaty lost three points to the "no" camp and the country was equally divided with 50 percent on each side.  

All 25 EU member states must approve the constitutional treaty, either by popular referendum or parliamentary vote.  

If such a heavyweight EU member as France rejects the constitution, many observers believe the treaty will be stopped in its tracks.  

According to Ipsos, most French believe those fighting the text use clearer, more credible arguments that are more relevant to the people.  

However, only 26 percent of those questioned Friday and Saturday believe that opponents of the constitution will succeed in blocking the text, while 47 percent believe it will be approved.  

Of those determined to vote, 14 percent said they could still be swayed in their choice, Ipsos said.
