Ant and Dec host the fourth live semi-final as more acts that made it through the auditions perform in front of the judges and a live audience for a chance at a place in the final. Viewers hold the power to vote for their favourite acts of the night to send through to the ultimate stage of the competition, and one judge has the Golden Buzzer that can reward one outstanding performer with a ticket straight through.
