The Canadian, who joined the WTA as President in 2006, was promoted to the chair and chief executive roles three years later and has since been named by Forbes Magazine as one of the "Most Powerful Women in Sports".

She is now hoping to spend more time with her family.

The 52-year-old has been credited with leading the body through a period of unmitigated growth, leading the women's game into new markets, particularly in the Asia-Pacific region, while also pioneering use of innovative data and technology.

As well securing over $1 billion (£600 million/€900 million) in diversified contracted revenues, including a landmark international media agreement help to increase broadcasting of the Tour around the world, the WTA Finals has also grown under her stewardship.

This has culminated in a five-year strategic partnership with Singapore to stage the BNP Paribas WTA Finals until 2018.

"It's been a privilege to lead the organisation that Billie Jean King founded and to have worked with the world's best female athletes, dedicated tournament promoters and passionate and professional WTA team members," she said.

"For 25 years I have dedicated my professional life to the sport and I'm proud of the work I leave behind.

"But the recent loss of my brother-in-law and the ATP's chief executive, Brad Drewett, has provided a personal wake-up call about life, family and priorities and it is time for me to shift some time and energy that way.

"When I joined the WTA my goal was to leave the organisation on a stronger footing and I feel a humble sense of pride in what we have all accomplished here.

"I have focused on what it means to be a champion and I have tried to be a strong role model for women to encourage success in the sports industry."

Another of Allaster's most enduring legacies is her battle to secure equal prize money for female players at all four Grand Slams.

Under the "Roadmap", the WTA's long-term plan that streamlines the calendar to enhance the overall health of the players while delivering top stars on a more consistent basis to fans and tournaments, prize money has doubled.

"Stacey has been a visionary leader for tennis this past decade." added King, the 39-time Grand Slam champion who founded the WTA in 1973.

"She brought positive fundamental change while serving as an exemplary role model, and she executed our biggest and best financial strategies during a very difficult economy.

"Stacey performed her job with tenacity and heart which is what is required for transformational change."

Allaster will formally step down on October 2, with a hunt having already begun for her successor.
