Rosalie Birch believes she can win back her England place in time for next year's World Cup.

The Sussex all-rounder has been left out of the squad for this summer's internationals despite helping England retain the Ashes by winning the one-off Test in Australia earlier this year when they also drew the one-day series 2-2.

There are four Sussex players - Caroline Atkins, Holly Colvin, Laura Marsh and Sarah Taylor - in the 15-man squad for games against West Indies, South Africa and India.

But Birch has been dropped because she has not scored enough runs or had enough opportunity to bowl her off-spin in county and club games for Brighton and Hove, whom she captains.

She said: "Holly is our first choice spinner and Laura has been really successful with her bowling too and when you are not first or second choice for your county you are not going to get many overs.

"I've been struggling a bit with my bowling and although I have scored a couple of fifties and a 70 I have not got as many runs as I would have liked. It's been a very frustrating season so far.

"Ebony Rainford-Brent has taken my place and that's fair enough because she has scored more runs than me."

Birch is on standby and will play in ODIs against Ireland and South Africa next month for an England Academy squad.

The 24-year-old was rewarded for her part in England's Ashes triumph with one of the first central contracts awarded to women players in April.

She spends 15 hours a week coaching youngsters and helping with public relations and has also started a job working in London for a PR firm.

She said: "I'm very busy at the moment but I still have England ambitions.

"Next year is going to be amazing for women's cricket with the World Cup in Australia and the first Twenty20 World Championship in England I want to be part of that."

Meanwhile Colvin is poised to become the first woman to play for an Australian state side as an overseas player.

The 18-year-old from Brighton will link-up with National League champions New South Wales Breakers in September.

Colvin became England's youngest ever Test cricketer when she faced Australia at the age of 15 in 2005 and has played 20 ODIs and three Test matches.

Former England and Sussex captain Clare Connor, who is head of women's cricket at ECB, said: "In terms of World Cup preparation there could be no better opportunity for Holly. She is a young but incredibly mature cricketer and I'm sure she will be well received and contribute to their squad."

Colvin will line-up for England in the first of two ODIs against West Indies at Loughborough on Friday. There are five ODIs against South Africa and India later in the summer with the last match of the India series taking place at Hove under floodlights on September 9.
