Reviewed: Scotland's Greatest Escape; Chess Masters: the End Game; Michael Sheen's Secret Million Pound Giveaway; The Au Pair BBC Scotland’s Judith Ralston has been given the keys to a moderately-budgeted travel show, Scotland’s Greatest Escape (BBC Scotland, Monday), which she presents in the company of the actor/comedian Grado. Back for a third series, the first stop for the pair was Perthshire, home to the constituency of John Swinney. With the way “Judith fae the weather” (Grado’s title for her) and “the Gradomeister” were going on, this was God’s own country. Queens View was better than the Grand Canyon, said Grado, Perthshire had been dubbed “the most welcoming region on earth”, and so on.
