A father-and-son duo from Norfolk will battle it out tonight for a £250,000 prize as they take on 10 other acts in the Britain's Got Talent final.

Jack and Tim Goodacre earned their place in the live final following their performance of self-penned song Big Wide World in Thursday's semi-final.

The pair, from Eccles near Attleborough, said they are 'incredibly grateful for this opportunity' as they prepared for tonight's show.
