Star Trek and Sherlock star Benedict Cumberbatch is to be next Sunday's celebrity guest on Top Gear.

Cumberbatch will be attempting to impress in the popular Star in a Reasonably Priced Car segment, and will show his motoring prowess over a lap of a race course in a 1.6 Tech Line Vauxhall Astra.

The Astra was introduced by hosts Jeremy Clarkson, Richard Hammond and James May as the show's latest Reasonably Priced Car at the start of the current season.

So far, AC/DC lead singer Brian Johnson is at the top of the celebrity leader board after completing a lap time of 1.45.1. Mike Rutherford is at the bottom of the scoreboard with 1:51.5.

Jimmy Car, Charles Dance, David Haye, Rachel Riley and Warwick Davis are among the others who have so far taken up the challenge in the show's current run.

Top Gear is on Sunday (July 14) at 8pm on BBC Two.
