Division Two champions Lancashire have confirmed the signing of England international Jos Buttler from Somerset.
The 23-year-old, who has played 19 one-day internationals and 25 T20 internationals, opted to leave his local side in a bid to further his career as a wicketkeeper, having been unable to dislodge Craig Kieswetter behind the stumps at Taunton.
The wicketkeeper-batsman is closing in on 4,000 runs in limited-overs cricket and has passed 2,000 in first-class cricket.
He impressed during the NatWest Series this summer, hitting a match-winning 65 not out and taking three catches at the SWALEC Stadium.
"I am delighted to be joining Lancashire,” said Buttler. “They have a strong squad and are very ambitious to build on this season's achievement. The club has an exceptional coaching staff which will help me to continue to develop as a keeper-batsman.
"Emirates Old Trafford is a world-class venue and has tremendous state-of-the-art facilities for cricketers. I really enjoyed playing there earlier this month for England and hope to be involved in next year's one-day international against Sri Lanka.
"Lancashire have a talented group of players who will be looking to challenge for all three competitions.
"Finally, I want to pay a special thanks to everybody at Somerset. I thoroughly enjoyed my time there and will leave with plenty of good memories."
Head coach Peter Moores added: "It is great news Jos will be joining us and he will become part of a highly competitive squad.
"His style of cricket will add value to the team in all formats of the game and his potential as a player is very exciting."
