Danny Cipriani will leave Wasps once his contract expires at the end of the season, the Aviva Premiership club confirmed on Monday.
Cipriani returned to the club that launched his career ahead of the 2016-17 season, but the signing of Lima Sapoaga ahead of the 2018-19 campaign put his future in doubt.
As expected, the fly-half will now join James Haskell in leaving the Ricoh Arena this summer, with offers on the table from sides in both England and France.
"I will be sad to leave Wasps, but my job is far from finished and I can promise the fans my absolute all until the end of the season as we tackle the mission ahead of us," Cipriani said in a statement.
"I will now take some time to decide my next move."
Cipriani, who told ESPN earlier this month that his second spell at Wasps had been the most enjoyable of his career, will look to bow out on a high with the club in contention for a place in the Premiership playoffs.
"Danny is moving on at the end of the year and we wish him well," Wasps boss Dai Young said. "We would also like to thank him for all his efforts in a Wasps shirt.
"As he says, now this decision has been made public we can all concentrate on the really important three-and-a-half months of rugby which lies ahead.
"This begins for Danny, the rest of the squad and staff at the Ricoh on Sunday, where our focus is fully on the challenge presented by Exeter."
