The Club has placed on record its thanks to Gillespie, 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.

The Club insisted it was now focussing on the remaining four 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 1st XI coach until the end of the current season.
