Durham have signed Alex Lees from Yorkshire on a three-year contract.
The left-handed batsman, 25, will initially join on loan for the remainder of the season and he will be available for the Durham's Specsavers County Championship fixture against Glamorgan at Sophia Gardens at the weekend.
Lees will add experience to the Durham ranks having played 89 first-class matches, scoring just short of 5,000 runs at an average of 34.53.
He helped Yorkshire win back-to-back County Championship titles in 2014 and 2015.
Durham head coach Jon Lewis said: "We're delighted that Alex has signed for the club and believe that his experience and skillset will make him a perfect fit at Emirates Riverside.
"When an English batsman of his age and ability becomes available, it's a no brainer and we're pleased that he has chosen Durham as we were aware that other counties were looking at him.
"Adding him into our squad gives us great options across both red ball and white ball and we are looking forward to seeing him continue to develop during the coming years at Durham and put himself back in contention for an England spot."
