Slickness is not always a virtue in a television presenter, and Katherine Jenkins (The Week We Went To War, BBC1) has some way to go before she risks being accused of it. Her chief weapons are her blonde hair, cleavage and searchlight smile -- she isn't so much the new Vera Lynn as one of those pneumatic dream-babes that American aircrews used to paint on the noses of their B17s -- but even so she struggles to conquer a script that wallows like a torpedoed freighter.
