George Bailey is to join Sussex Sharks for the second half of their NatWest T20 Blast campaign this summer.
Australia batsman Bailey, who will also be available in the Royal London One-Day Cup, has signed a deal to take over from Sri Lanka great Mahela Jayawardene - who will be Sussex's overseas player for their first seven Blast group fixtures.
Bailey, 32, has captained his country in both limited-overs formats - including in the champions' World Cup group match victory over England this year - and previously spent the 2013 campaign with Hampshire.
He said: “I'm delighted that I will be heading to Hove to represent Sussex - I really enjoyed my time in the county game with Hampshire and I am looking forward to testing myself once more in one of the toughest domestic cricket environments.
“I have heard excellent things about the set-up at Sussex and we have a really exciting squad that I believe can mount title challenges in all formats in 2015.”
Sussex's professional cricket manager Mark Robinson added: "The whole club is really excited at the prospect of George joining us.
"He is obviously a fantastic one-day player and is also a World Cup winner and international captain - which will only add to our dressing room."
