World number three Rebecca Kenna says she has quit her local snooker league after being barred from matches because she is a woman.
She made the move after being stopped from playing in two fixtures due to some clubs in Keighley operating a "men-only" policy.
Mrs Kenna said Keighley was not the only place in the UK where women struggle to compete equally.
Reanne Evans, 11-times women's world snooker champion, told BBC Radio 4 in February she had previously been refused entry to a snooker hall for the same reason.
