Sweden's Julia Engstrom survived a nervous final round to win her second LET title of the season in the Lacoste Ladies Open De France.
Engstrom began the day with a four-shot lead but struggled to a closing one-over-par 72 to finish a shot ahead of home favourite Celine Herbin and Argentina's Magdalena Simmermacher, who surged through the field with a 66.
"It's been the perfect week, I love this place," the 19-year-old said at Golf du Medoc.
"I came out here with a good feeling and obviously yesterday's hole-in-one was a highlight. It was nerve-wracking at the end, but I am relieved to get it done."
England's Florentyna Parker finished alone in fourth place following a final round of 69, with compatriot Charlotte Thompson and Scotland's Kylie Henry two shots further back in a tie for sixth.
