Yorkshire coach Jason Gillespie will leave his role at the end of the season, the county have confirmed.
The 41-year-old, who led Yorkshire from the second division to consecutive County Championship titles, is returning to his native Australia.
Yorkshire will wait to appoint the successor to Gillespie - who took over in 2011 - after the season ends.
"Jason feels the close season is an appropriate time to part company," a Yorkshire statement said.
Gillespie's wife and their four children have recently returned to Australia, where the former fast bowler also coaches the Adelaide Strikers in Australia's Big Bash Twenty20 competition.
