Andy Burnham will be the first prime minister on Gogglebox, debating crisps with Steve Rotheram inside No 10

In the trailer, the Prime Minister offers Skips, pork scratchings and bacon fries before declaring Twiglets 'probably the best'. Rotheram, the Liverpool city region mayor and a close friend, turned up with Quavers instead. The Stand Up To Cancer special was filmed in Burnham's Downing Street flat and airs at 9.05pm. Downing Street has refused to reveal which shows the pair will review.

Jeremy Corbyn got to the sofa first, appearing as Labour leader in 2017.

Sugababes and comedian Joe Lycett also feature in the charity special.

Burnham tosses Rotheram a crisp packet, which hits the floor, and both roar with laughter.
