Warwickshire have made veteran New Zealand off-spinner Jeetan Patel captain in County Championship and 50-over cricket for 2018.
Former Surrey batsman Dom Sibley has been named vice-captain while Grant Elliott will continue as skipper of Birmingham Bears in the T20 Blast.
Patel, 37, is a long-serving overseas player for Warwickshire, winning the County Championship in 2012, the NatWest T20 Blast in 2014 and the Royal London One-Day Cup in 2016. He was named PCA County MVP in both 2014 and 2016 and runner-up in 2017.
He takes over after a turbulent 2017 which saw Ian Bell resign as captain in August to be temporarily replaced by Jonathan Trott (Championship and 50-over) and Patel’s compatriot Elliott (T20). Warwickshire were relegated to Division 2 of the County Championship but did reach the final of the T20 Blast.
Sibley, 22, arrived at Edgbaston in August and is now being groomed for the captaincy long-term. After acrimoniously parting wasy with his boyhood club, he made an immediate impact in T20 cricket for Warwickshire, scoring 191 runs in seven games.
Giles added: “Dom made a significant impact after joining the club at a difficult time last season and we saw some real fight and character in the innings that he played.
“He’s fitted well into the changing room and by working closer with Jeetan, Grant and the other experienced players, we believe that he can also develop into an excellent leader.”
