Jason Gillespie will end his successful five-year spell as Yorkshire head coach next month after the county announced  that he is returning home to Australia.

Gillespie has won the County Championship twice during his time in charge and is on course to bow out with a hat-trick of titles despite again losing key players to England.

Yorkshire are only five points behind Division One leaders Middlesex, who they face at Lord's in Gillespie's final match before he leaves England to be with his family.

"Yorkshire County Cricket Club can confirm that Jason Gillespie will leave his position as first-team coach at the end of the 2016 season," the statement read.

"The club would like to place on record its thanks to Jason, who led Yorkshire from the second division to consecutive Championship titles, along the way suffering just five defeats in 76 Championship fixtures since his appointment in November 2011.

"His wife Anna and their four children have recently returned to Australia and, with the 41-year-old's existing commitments to coaching the Adelaide Strikers in Australia's Big Bash, Jason feels the close season is an appropriate time to part company.

"There will be opportunities to speak to both Jason and director of cricket Martyn Moxon in the coming days. However, the focus will now be very much on the remaining four Specsavers County Championship fixtures, beginning with Wednesday's trip to the Ageas Bowl to face Hampshire, and on securing the first Championship treble seen at Headingley since the 1960s.

"Martyn Moxon will not begin the search for a new first-team coach until the end of the current season and the club will provide further updates when the time is appropriate."

Gillespie, who spent two years with Yorkshire as a player, took the reins at Headingley after the county were relegated in the County Championship and secured an immediate return to the top flight in his first season at the helm.

Yorkshire finished second in 2013 before claiming their first title since 2001 the following season and retaining the trophy last year.

The White Rose have failed to hit the same heights under the Australian in limited-overs cricket, although they have twice reached T20 Finals Day and were losing semi-finalists in the Royal London One-Day Cup for the second year running on Sunday.

The 41-year-old took 259 wickets in 71 Tests for Australia and his Headingley exit could open the door to him assisting Darren Lehmann as the national team's bowling coach, a role he has long been linked with.
