Jamie-Leigh was three shots clear of the runner-up, England girl international Holly Clyburn, from Woodhall Spa in Lincolnshire. Holly, 17, is a member of the English Womens Golf Association Futures U18 Squad.
Suffolks Heidi Baek (Felixstowe Ferry) was third and, like Holly, shot thee-under par in the second round. Heidi, 14, from EWGAs Select Midlands Squad is the English U15 champion and has been selected for Englands team for the Girls International Matches.
Among the other players in the top ten were three more members of EWGA squads: Yorkshires Sophie Godley, 14, (Lindrick) was sixth, one place ahead of English womens champion and defending titleholder Hannah Barwood, 17, of Knowle, Gloucestershire. Warwickshires Elizabeth Mallett who is the English U16 schools champion was ninth. Elizabeth, 13, plays at Sutton Coldfield Ladies
Jamie-Leigh, from Kirby Muxloe, took the title with scores of 74 and five-under 67, which shaved a shot off the old record.
Her afternoon round included an eagle, four birdies and just one bogey – and she has reduced her handicap to plus-one.
Her father, Jamie, commented: She is over the moon and she wants to say a big thank you to her coach, Steve Cooper of Gainsborough.
Already this season, Jamie-Leigh has qualified for the matchplay stages of the English championship and won the Leicestershire championship. She also helped her team reach the finals of the English county golf championship.
Now, she will captain the girls teams in the annual schools internationals against Wales in August and Scotland in September.
