This week's Ant v Dec challenge for Ant & Dec’s Saturday Night Takeaway will be The DofE Overnight Challenge.

The Geordie duo will be swapping their suits for rucksacks and will head off in opposite directions trekking across the countryside followed by their celeb team mates.

Team Ant and Team Dec will take part in various challenges and navigate their way to a finishing point.

The DofE Overnight Challenge is based on a Bronze DofE Expedition; however, an element of competition has been introduced because of the entertainment factor.

The challenge was announced to Ant & Dec and the teams on Saturday 21 February and the winner will be announced during the show on ITV1 on Saturday 28 February. Kirsty Gallacher presents for this part of the show.

Tune in on Saturday at 7.45pm on ITV1 to see how the teams get on.
