The 26-year-old is joined by back-row forwards Andrew Wilson and John Beattie in signing new contracts with the club.

But Glasgow head coach Hugh Campbell believes fly-half Parks' re-signing will prove essential in Glasgow's European Cup and Celtic League campaigns next season.

He said: ''It's great to be able to re-sign a player of Dan Parks' standing.

''He looks to be getting back to his top form in the club and now has a mass of international experience that will prove invaluable for our Celtic League and European Cup campaigns.''

Wilson and Beattie have both signed three-year deals.

Campbell added: !We're pleased to be able to sign a talented young Scottish player such as John Beattie.

''!I'm sure he's got a future in the top professional ranks. We're also delighted to sign Andrew Wilson on a three-year deal.

''He's made massive strides for us this season and is the type of physical back-row player who can enhance the Glasgow performances.''
