Tennis coach Judy Murray has served a rallying call for action to address the "gender imbalance" in the sport.

Speaking at the first She Rallies conference in Birmingham, she set out her ambition to attract and retain more women and girls in tennis.

The conference saw female speakers from various sporting and business backgrounds discuss ways to strengthen and grow the female workforce within the sport.

Mrs Murray provided an insight into her experiences in the industry, allowing the female coaching audience unique access to her personal and professional tennis journey.

The weekend launch of the campaign, which is being headed by Mrs Murray in partnership with the Lawn Tennis Association, saw 26 She Rallies ambassadors receive bespoke training on how to deliver starter tennis and fun days for girls.

Mrs Murray said: "It's been a fantastic three days and the perfect kick-off to the She Rallies campaign.

"We have now trained a team of female ambassadors to go out and empower women and girls to play, compete and deliver tennis.

"This is our first step to addressing the gender imbalance in our sport."

Mrs Murray has been actively calling for action in recent years to capitalise on interest in tennis fuelled by her sons' success.

Sir Andy Murray and his brother Jamie both finished 2016 as world number one tennis players, with Sir Andy rounding off the year with a knighthood in the New Year Honours List.

Mrs Murray also runs the Tennis On The Road project, designed to introduce children to tennis in areas where courts and coaches are rarely found, and Miss-Hits, which aims to make the sport more welcoming for young girls.
