The three comedians will be locked in the world-famous toy shop on London’s Regent Street overnight, with no security guards to hinder their fun. 

The trio will have all night to do what they imagined and dreamed of doing in a toy shop when they were kids, with the only rules being no sleeping, that’s cheating, leave everything where you found it, and if they break something, they have to pay for it. 

The night of riotous fun will be narrated by Sarah Millican and will see the comics reminisce about their favourite Christmas stories, create their own unique games to play, raid the shelves and just generally revel in the festive spirit. 

They are free to do whatever they please but must leave before the cleaners arrive and the shutters are raised for a new day. 

One Night In…Hamleys airs Christmas Eve at 9pm on Channel 4.
