The 24-year-old will rejoin the Warriors after signing a two-year deal with Sean Lineen's side.

The former Scotland U21 captain spent a season with Glasgow before joining Leeds Tykes in 2004 and subsequently won the Heineken Cup with Wasps in 2007, a year after joined.

He said: "I'm really looking forward to joining up with Glasgow again. The Warriors have a very hungry and ambitious squad and I'm no different."

McMillan hopes his return to his homeland will help to catch the attention of Scotland coach Frank Hadden.

Hadden is well blessed with options at No 9, with Mike Blair, Chris Cusiter and Rory Lawson all playing in the 2008 RBS 6 Nations.

McMillan said: "By returning to Scotland, I'm not only looking to enhance my own international ambitions, but I thoroughly believe that Glasgow have a squad of boys that will continue to push at the top end of the Magners League and in Europe."
