PARIS: French President Nicolas Sarkozy defended his economic record on Friday as a slew of opinion polls suggested his prospects of re-election were crumbling just over a week from round one of a vote where Socialist Francois Hollande is the clear frontrunner.      Four polls published in less than 24 hours showed Hollande extending his lead, with the conservative incumbent's modest gains of the past month starting to evaporate ahead of a two-round contest taking place on April 22 and May 6.

A CSA poll showed Hollande winning the May 6 run-off with 57 per cent of the vote. Three other polls also indicated that his chances of becoming France's first left-wing president since Francois Mitterrand were improving.

Sarkozy maintained that he had helped France weather economic crisis over the past four years far better than countries such as Greece or Spain, and he renewed warnings of market turmoil if Hollande won power.

“What fires up the financial markets and speculation is when a country does not repay its debts, reneges on its commitments and embarks on a path of ill-considered spending,” Sarkozy told a TV news channel.

“Mr Hollande, by promising to raise spending without any commitment to cutbacks, is setting the stage for a confidence problem (in financial markets),” he said.

Hollande, who says he can slash the public deficit but also promote jobs and education as he hikes tax on the rich, stuck to his line in three newspaper interviews published on Friday. He said austerity would be self-defeating if not accompanied by efforts to promote economic growth in France and Europe.
