The number six seed came past Portugal's ninth seed Fu Yu in the final in the Hungarian capital today, prevailing 11-3, 11-2, 11-4, 10-12, 11-7 in five games.

She lost just five games on her way to the title with the victory potentially being a watershed moment in her career.

"I am happy the way I played today," said Melek. 

"I am not afraid any more of the pen-holders. 

"I was very confident and I had a good feeling for the ball."

Melek had won a semi-final earlier in the day against Dutch player Lie Jie, with Fu beating Elizabeta Samara of Romania in her last four contest.

In the men's competition, France's Emmanuel Lebesson completed a shock victory by beating compatriot Simon Gauzy in the final.

The number 14 seed was an outsider at the start of the tournament but beat his team-mate, the number six seed, 14-12, 9-11, 11-7, 11-3, 11-6.

"I did not start the match very well and that is the last thing I wanted to happen, if you give Simon the chance to lead, he will just increase the pressure," said Lebesson.

"At the end of the opening game I managed to win only one point on my service. 

"Only God helped me win that game. 

"Later Simon recovered, but I raised my game to a higher level; from the third game I played the best table tennis of my life. 

"It was an  incredible match."

Lebesson earlier knocked out Jakub Dyjas of Poland in the semi-finals, with Gauzy ousting Germany's Timo Boll.

Number seven seeds Kristin Silbereisen and Sabine Winter won the women's doubles final in an all-German affair against Shan Xiaona and Petrissa Solja.

Their opponents were ranked second, but Silbereisen and Winter upset the form book to win 12-10, 8-11, 11-8, 11-8, 2-11, 7-11, 11-9 in a lengthy affair.

Germany’s Patrick Franziska and Denmark’s Jonathan Groth were crowned as men's doubles champions, beating Poland's Dyjas and Daniel Gorak, 4-11, 11-4, 11-5, 7-11, 11-7, 12-10.
