Acts through to the final

After the first semi-final, we now know that the first acts heading through to the final will be hero police dog Finn and his owner Dave, and Flakefleet Primary School.

Finn and Dave automatically secured their place after winning the most public votes, but Flakefleet had to fight off competition from the creepy act The Haunting before being chosen by the judges.

Another eight acts will perform tonight, including Amanda's golden buzzer act 10-year-old singer Giora Borg.

You will be able to watch the Britain's Got Talent live final on ITV on Sunday at 7.30pm.
