Dawson was recalled to the England squad in January

The 32-year-old, who has 65 England caps, joined the club from Northampton in the summer on a one-year deal.

"The experience I've had at Wasps since moving here last summer has proved to me that coming here was the right move.

"I've seen a huge improvement in my understanding of the game and therefore to sign a new two-year deal is nothing but a positive step," Dawson said.

I'm glad to see that Dawson is still going to be with us for a bit longer as he still has it in him From beaten_black_and_yellow Have your say on Scrum V

He also admitted this is likely to be the "last contract that I sign".

The new deal will enable the World Cup winner to team up with former Northampton boss Ian McGeechan, who will replace Warren Gatland at Wasps next season.

"Geech was very influential in the middle of my career, at a time when many promising scrum halves can falter in their development," said Dawson.
