Former England batsman Vikram Solanki has resigned as Worcestershire captain after more than five years in the job.
Solanki made the decision in the wake of the county's 241-run defeat to Glamorgan at Colwyn Bay.
The Pears were skittled for 175 on the final day to slump to their fourth defeat of the season in LV County Championship Division Two.
"It has been a real honour and a privilege to captain this club but it just seems the time is right," Solanki, who was the longest serving captain in domestic cricket before his decision to step down, told BBC Hereford & Worcester.
"Results haven't gone as well as we would all have liked and it is perhaps time for somebody else to be at the helm."
Daryl Mitchell, Solanki's vice-captain, will take charge for the remainder of the season.
Meanwhile, former Pears batsman David Leatherdale will take over as the county's chief executive following the resignation of Mark Newton following 10 years' service.
"I have gained a great insight into the internal structures of the club over the last five years and particularly the last two as deputy CEO during what, it is fair to say, have been particularly difficult times," said Leatherdale.
"The cricketing landscape has changed immensely, both structurally and economically which has created many challenges and I am sure there will be many more to face in the future.
"We are a club with 145 years of history and a huge number of loyal and passionate supporters, myself included, and a young developing team who have all the attributes to move the club into a new era."
Worcestershire, who were relegated in 2009, are currently sixth in the Division Two table.
