The 26-year-old former world and British Isles junior champion defeated defending champion Ellen Falkner of Ely in straight sets, 9-4 10-5.

It was Brown's second singles final in three years.

Brown, from Motherwell, secured a 7-6 9-8 win over Carol Ashbyk in the semi-final on Tuesday to set up the encounter with Falkner.

There were two shock results in the world indoor singles as world number one Greg Harlow and three-times former world champion Paul Foster both failed to reach the last eight.

Harlow, last year's runner-up, lost 7-6 6-5 to Billy Jackson while Scotland's Foster lost to 20-year-old qualifier Jamie Chestney 7-5 9-5.

Harlow said: "He played exceptionally well. He never really missed an opportunity, he never missed a shot.

"I really wanted to win this title, so I'm disappointed to go out at this stage. But I wasn't disappointed with the way I played."

Jackson said: "I've learned a lot over the past two years and this has really helped my game."

Foster said: "I started brilliantly and could have gone 5-0 up but the game completely changed after that third end - and he didn't give me a chance thereafter."
