Dundee United have signed defender Callum Booth on a two-year contract following his departure from Partick Thistle.
The 26-year-old came through the youth ranks with Hibernian before making the move to Firhill in January 2015, initially on loan.
Manager Csaba Laszlo told the club website: "I am delighted to bring Callum to Dundee United. He is an experienced left-back who has played in the Premiership for many seasons."
