Owais Shah has retired from first-class cricket in order to focus on the shorter forms of the game.
The elegant right-hander, 34, has spent the last three seasons with Essex after more than a decade at Middlesex.
He boasts 16,357 runs from a first-class career that featured 45 hundreds and six Test outings for England between 2006 and 2009.
Shah has excelled in Twenty20 cricket in recent years, participating in a variety of competitions around the globe, and will continue to be available for limited-overs action.
“I have really enjoyed my Championship cricket career. I started off playing four-day cricket for Middlesex and my main aim was to play for England. I have achieved this but now as time goes on I would rather concentrate on the shorter forms of the game,” said Shah.
“It's time for the young guys at Essex to come through in the first-team squad and it’s important that I don't stand in their way.”
