Former Doctor Who star David Tennant and actor Sean Pertwee are the face and voice of a new Labour Party election commercial.

Sean, son of the late Jon Pertwee, also a former Doctor Who, walks along a country road exhorting voters not to leave the road to recovery from recession the Government has undertaken.

In a voiceover, Tennant echoes Labour’s pledge to ‘build a Britain that’s fair for all of us’.
