England fly-half Danny Cipriani has ended speculation over his future by signing a new deal with Wasps.
Cipriani is one of 13 players to have agreed to remain at Adams Park for the 2009-10 season and beyond.
Richard Birkett, Tom French, John Hart, Tim Payne, Tom Rees, Simon Shaw, Mark Van Gisbergen, Phil Vickery, Dave Walder and Dominic Waldouck have also signed new deals, while Joe Simpson and James Honeyben will graduate from the academy set-up.
The news comes as a massive boost for the club after seeing James Haskell, Tom Palmer and Riki Flutey all announce that they would be leaving in the summer to move to France.
Cipriani had been courted by a number of clubs on both sides of the Channel, however he has agreed a new 12-month deal, while fellow England team-mate Rees has signed two-year contract.
Fellow England elite squad members Vickery and Shaw have also penned new two-year deals with Payne committing himself to Wasps for three years.
And director of rugby Ian McGeechan has welcomed the news as vital for the club's plans.
On the news McGeechan said: "We are delighted with the volume of players committing to the club for next season and for those to come.
"This is a great show of intent from the players and our board as we see a mixture of experienced and international calibre players combine with up and coming names.
"All of these play a pivotal role in our campaign both now and in the future and are core to the continuing development of the team and our rugby."
There is also a new 12-month deal for Birkett, while Walder, Van Gisbergen, Waldouck, French, Simpson and Honeyben have all agreed to stay with Wasps for the next two years.
Wasps director Lawrence Dallaglio, who was involved in the player negotiations, was delighted that so many of the squad would be staying on.
He said: "London Wasps is much more than a just a rugby club to me - it was a workplace, a home, a family and one which I am still very proud to be a part of.
"As we see so many players commit themselves to the cause once more today, it gives me a great sense of pride and satisfaction that we can list names like Shaw, Vickery, Rees, Cipriani and Payne in our squad - players who have shown themselves to be of the highest calibre on the domestic and international stage.
"London Wasps has never been based on individuals but on team spirit and camaraderie and when you look at the names listed today - Birkett, Hart, Van Gisbergen, Walder, you see men who have embedded that very notion, season upon season, and I am delighted that this will continue following today's announcement.
"As well our more recongisable names, our up and coming talents like Tom French and Dominic Waldouck continue to show their faith in the Club and its development.
"The proof of their success and those before them provides inspiration for players like Joe Simpson and James Honeyben who today graduate from the Academy set up and join our senior squad."
