Overnight leader Gwladys Nocera carried her fine form from Saturday into the early stages of the final round as she continued to lead the Lalla Meryem Cup in Morocco, a title she won in 2007 before the event joined the Ladies European Tour in 2010.
Separated by two strokes after the third round, Gwladys and Frenchwoman Sophie Giquel-Bettan both birdied the second to remain two strokes apart.
England’s Charley Hull moved within two of the lead at 10-under after she eagled the sixth, having birdied the first two holes.
England’s Sophie Walker fired three birdies in her first six holes to get within four of the lead, looking to improve on her career best finish of tied 2nd at the Scottish Open in 2010.
The 15-year-old amateur, Mathilda Cappeliez, from Evian in France, was still in contention on five-under after six holes.
The defending champion Ariya Jutanugarn double bogeyed the first hole and recovered with a birdie on the second, but then dropped another stroke at the fifth.
Conditions are hot and sunny with a slight breeze and temperatures of around 30C.
