Colin Turkington on brink of second British Touring Car title

Colin Turkington sharpens his driving skills with some karting ahead of the final round of the British Touring Car Championship at Brands Hatch this weekend.

The Portadown driver goes into Sunday's final three races with a healthy 50-point lead over his nearest rival but the BMW drivers insists there will be no complacency on his part as "the job is by no means done".

Turkington is aiming to secure his second title, five years after he collected the crown in nailbiting fashion.
