The Toulouse wing produced a devastating finish after it looked as though Ronan OGara had done enough to steer Ireland to a stirring win.

Substitute Lionel Beauxis added the conversion, destroying Irish Grand Slam hopes when they desperately wanted to christen their temporary Dublin home with a first victory over France since 2003.

Ireland wiped out a 10-point deficit, but they face a huge psychological task in recovering in time for Englands February 24 visit.

Munster star OGara scored a sparkling try and slotted four penalties during a rip-roaring contest when Ireland recovered brilliantly from an error-strewn opening quarter.

France, though, dug deep when it really mattered, ultimately stunning Ireland after captain Raphael Ibanez touched down for the visitors to reward initial dominance, while fly-half David Skrela slotted two penalties and a conversion.

Ireland looked to have overcome the absence of injured skipper Brian ODriscoll and scrum-half Peter Stringer, but they had to regroup after making a terrible start.

Ireland conceded 13 points in the first 14 minutes as their scrum and lineout malfunctioned, with France forging clear through hooker Ibanezs well-worked try after Skrela slotted two early penalties.

ODriscoll was badly missed during the early stages - Ireland appeared flustered and indecisive in his absence - and it was not until eight minutes before half-time that an 81,000 crowd had something to celebrate.

OGara wrong-footed the French defence when he feigned a drop-goal attempt, and slick passing by Denis Hickie and Shane Horgan worked space out wide, where flanker David Wallaces exquisite offload freed OGara in the corner.

Having seen their advantage slashed to 13-11, France should still have enjoyed a healthy interval advantage, but Ireland wing Geordan Murphys defensive intercept thwarted a three-man overlap and Skrela missed two injury-time penalty chances.

OGara edged Ireland ahead for the first time on 56 minutes, and both sides defied fatigue to maintain a thrilling tempo.

France were denied when substitute Lionel Beauxis 74th-minute drop-goal hit the post before OGara nailed a long-range clincher three minutes later and Clerc administered a world-class finish.
