The flagship events for both men and women will be held alongside each other in the English city between December 9 and 17.

AJ Bell, which is based in Manchester, is one of the UK's largest providers of online investment platforms and stockbroker services.

The company was also the title sponsor for the 2013 Men's World Championships in Manchester.

Billy Mackay, AJ Bell's marketing director, said: "We were very pleased with the success of our partnership with England Squash, Manchester City Council and the Professional Squash Association during the 2013 World Championships, and we are delighted to enhance our relationship with the sport once again ahead of what is certain to be an even bigger and better event than before.

"To have both the men's and women's competitions taking place concurrently in Manchester is a huge draw for fans across the country, and this will be a major benefit to the local economy."

Matches at the Championships will be played at the National Squash Centre and Manchester Central.

For the first time, equal prize money will be on offer for men and women.

"We are delighted to support the first-ever World Championships to offer equality in prize money between male and female competitors," Mackay added.
