Ant and Dec have pulled out from presenting a special spin-off of Britain's Got Talent as a fan favourite steps in.

The presenting duo, who host the regular version of ITV's popular talent show have been forced to postpone all of their work due to illness.

The veteran presenters, who are gearing up to present I'm a Celebrity 2022, will be replaced in the two-hour magic special by another familiar face.

Former Britain's Got More Talent host and friend Stephen Mulhern presented the spell-binding spectacular, which was filmed this week, instead.
