Two of the north-east of England's most famous stars have announced they are putting their names to a high profile campaign.

Ant and Dec have become patrons of the Children's Heart Unit Fund at Newcastle's Freeman Hospital.

It is a welcome boost for the unit which has faced uncertainty after the suspension of a national review into children's heart surgery.
