Apple has debuted the trailer for its forthcoming drama Slow Horses, starring Gary Oldman, Kristin Scott Thomas and Jack Lowden.

The espionage drama follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known un-affectionately as Slough House.

Oldman stars as Jackson Lamb, the brilliant but irascible leader of the spies, who end up in Slough House due to their career-ending mistakes as they frequently find themselves blundering around the smoke and mirrors of the espionage world. 

The show premieres on Apple TV Plus on 1st April.
