The David Tennant Treat 4 Today is a batch of photos which the BBC released to promote the Doctor Who episode Gridlock.
The episode was the third episode of Series Three. David Tennant starred as the Tenth Doctor in this episode and Freema Agyeman starred as his companion Martha Jones (although they spend most of this episode apart!)

More photos were released by the BBC for this episode but these are the only ones which featured David Tennant.
