Simpson made his England debut against the Barbarians in 2010
Wasps scrum-half Joe Simpson has signed a new three-year deal, keeping him at the club until 2014.
Simpson, 22, joined the London Wasps Academy in 2006 and has gone on to score nine tries in 47 appearances.
"Having grown up in the academy this feels very much like home and I am enjoying my rugby and being a part of this squad," he said.
Simpson made his Wasps debut in 2008 and has represented England U19s and U20s and the England Saxons.
The scrum-half was promoted to the Wasps first team squad ahead of the 2009/10 season and he has made 11 appearances this term.
We want to be involved in his ongoing development
Wasps Director of Rugby, Tony Hanks
Wasps director of rugby Tony Hanks is happy the Australian-born player will remain at Adams Park:
"His performances in black and gold have put him on the radar for England and he has certainly become a crowd pleaser amongst the Wasps faithful but for me it is his work ethic, his attention to detail and the basics that have impressed the most," he said.
Simpson, who was shortlisted for the IRB World Junior Player Award in 2008, was inline to be selected for Martin Johnson's England side for the 2010 Six Nations.
However, he dislocated his shoulder in December 2009 which ruled him out of contention for the tournament.
The scrum-half suffered another injury blow when he was forced to withdraw from England's summer tour to Australia this year because of a hamstring injury.
Despite the injuries, Hanks is confident Simpson will continue to progress both on the domestic and international stage; "We want to be involved in his ongoing development and success both for his club and at international level in the future," he said.
