Who is the Wildcard act on Britain's Got Talent?

Presenter Declan Donnelly confirmed that it was B-Positive Choir in the opening of the final.

Simon Cowell said the decision was "harder than we thought" but that ultimately they "100% deserved to be here".

Cowell had previously hinted the choir would be the Wildcard after saying he would do "everything in my power" to make sure the singers made it through after they missed out on a place in the BGT final.

On Thursday night's BGT semi-final, presenter Declan Donnelly explained that "after tomorrow night's show you guys [the judges] are going to get together and choose a Wildcard that will make it into the show on Sunday."

However it was met with calls from both Simon Cowell and Alesha Dixon that there should be multiple Wildcards. "Can we have two?" asked Simon, with Alesha added: "Two please...we can squeeze it in. Wildcard...s!"

Speaking on Britain's Got Talent earlier in the week, judge Simon Cowell said: "There will a million percent be a Wildcard. We'll see what happens but there will 100% be a Wildcard."

However it's yet to be announced exactly how the Wildcard will work this year - whether it'll be open to a public vote, or whether the judges will choose their favourite act of the week who wasn't voted for by the public to go through to the grand final.
