Tommy Fleetwood claimed victory at the 2017 Open de France at Le Golf National in Paris on Sunday.
The winner scored a bogey-free final round of 66 to grab the champion's prize of £915,530, according to the European Tour.
The Englishman completed victory on 12 under par for the competition as he showed nerves of steel.
Peter Uihlein finished in second place to claim £610,350.

Fleetwood stormed through the final day as he completed five birdies, clearly the most dominant entity on the course as he became the leader in the Race to Dubai.
The 26-year-old Englishman remained calm and confident on the front nine, and motivated and focused down the back nine to claim his victory.
The new champion was excellent from tee to green, and his composure gave him the title by one stroke.
Fleetwood opened his round with two birdies in the first three holes, and the talent never looked back.
A further birdie on No. 9 positioned him well at the turn, and he controlled his adrenaline to stay in command.
The European Tour highlighted Fleetwood's driving at the turn:
Uihlein was slightly off the pace as he shot a final round of 68 to finish just behind Fleetwood for the championship.
The American posted four birdies on the back nine, but bogies on Nos. 4 and 5 were the undoing of his charge across the day.
Uihlein almost forced a play-off as he charged toward the finishing post, but he failed to card a birdie on the final hole.
The European Tour showed the runner-up questioning Fleetwood's dominance:
Fleetwood has emerged as one of golf's most exciting players, and his climb up the rankings has been breathtaking over the past 12 months.
Uihlein's performance was excellent in Paris, and on another day his final round would have given him a much-needed victory.
Andy Sullivan and Thomas Pieters were expected to challenge on Sunday, but neither player could maintain their performances as Fleetwood strode forward.
