The nation's top curlers are in Perth for the Scottish Championship - and the chance to represent Scotland at April's World Championships in New Brunswick, Canada. David Murdoch's Lockerbie rink have won four of the last six Scottish titles and are sure to start as favourites again, especially having retained their European title in Sweden in December. With selection for next year's Winter Olympics just around the corner Murdoch will be keen to prove his class, but is likely to be pressed hard by the likes of Perth's Warwick Smith - Scottish champion in 2007. Dougie Donnelly presents the best of the action from the Dewars Centre in Perth and is joined in the commentary box by former Scottish champion Bob Kelly.
