England have added former opener Marcus Trescothick and Kiwi spinner Jeetan Patel to their full-time coaching staff.

Trescothick, who played 76 Tests and helped England win the Ashes in 2005, has left his assistant's role at Somerset to take up the position of batting coach.

New Zealander Patel, who is currently working with the team in India, will work as elite spin-bowling coach, while Jon Lewis has been promoted from his role in charge of England's under-19s to fill a similar role with the quicks.

All three will supplement the work being done by England head coach Chris Silverwood and his assistants Paul Collingwood and Graham Thorpe.

"I'm really excited about the calibre of the individuals that we've appointed into these specialist roles," England & Wales Cricket Board performance director Mo Bobat said.

"Marcus, Jon and Jeetan have demonstrated their ability at the highest level and also show huge potential for the future.

"Working in conjunction with counties, they will have responsibility for developing and preparing current and next-in-line England players whilst also adding value to our England and Lions environments.

"I'm looking forward to our new coaching team working together in the build-up to our summer international program."

England are next in action from Thursday, when they take on India in the fourth Test in Ahmedabad hoping to level the four-match series that the hosts currently lead 2-1.
