Aston Villa defender Stephen Warnock has joined Championship club Leeds United on a permanent deal.

The 31-year-old former England international had recently been on loan at Bolton Wanderers.

"I'm absolutely delighted again. Stephen has the experience I think we need in that position," United manager Neil Warnock told the club's official website.

"He is a former international who, for whatever reason, has been allowed to leave Aston Villa."

Warnock had previously been linked with a move to West Ham United.
