The 24-year-old carded rounds of 71, 71, 73 and 70 at the punishing National Golf Club in Antalya to win by 12 shots on seven under par.

It was the second largest winning margin in the LET's 30-year history, Laura Davies winning the 1995 Guardian Irish Holidays Open by 16 shots.

Another Swede, Johanna Westerberg (71), shared second with South African Stacy Lee Bregman (72) and Spaniard Paula Marti (74).

"It's fantastic. I'm so happy. I only understood I'd won on the 18th green because I didn't think about it before then," said Wahlin.

"I was just enjoying it. I wanted to finish well. My goal for today was to shoot in the 60s so I had to make a birdie on the last, but I didn't. That was my only goal.

"The four days have just been so good. I've been playing good golf and I had a good focus. It's the best moment in my career.

"I have been on tour for three years so I think it was time to win. I want to win three times this year so I'm going to keep on going."

The Ladies European Tour now takes a week's break before the Deutsche Bank Ladies' Swiss Open at Golf Gerre Losone from May 22-25.
