Is Britain's Got Talent fixed? Russian contortionist act revealed as Cirque du Soleil pros

Britain's Got Talent has received fresh accusations of being fixed after it was revealed that one act – which blew the viewing audience away – are professionals that have performed in prestigious acrobatics show Cirque du Soleil.

The four-piece group, Angara Contortion, from Buryatia, Russia, wowed the judging panel including Simon Cowell and the excitable crowd on Saturday night's (6 May) with an immaculate, highly-skilled performance that led to a standing ovation.

After sailing through to the next round without any qualms and being by far the most professional act of the night, viewers flooded social media to praise them.

One individual tweeted: "The Russian contortion group is should of getting that gold buzzer best act from a mile fareplay #BGT" as another wrote: "How did Angara Contortion not get the golden buzzer? They are 1000× better than the dance act who did the other week".

A third added: "That contortion group was amazing, and their make up was stunning too".

And the judges couldn't have agreed more, with David Walliams telling the ladies: "That was one of the most stunning things I've ever seen on this show."

But the group – comprised of four females named Bayarma, 29, Imin, 28, Ayagma, 27 and Serchmaa, 20 – are no strangers to pleasing a crowd.

Before auditioning, the girls claimed that they had travelled to the UK especially for the show, flying six hours to Moscow and then a further three hours to touch down in Britain in a bid to have land a spot at the Royal Variety Performance.

The Mirror claims that the self-proclaimed amateurs actually live in the US. They have also starred in the critically-acclaimed and world famous Cirque du Soleil and featured in its Kurios show that has staged more than 1,100 events across the globe since 2014.

Angara Contortion have also performed on The Late Late Show hosted by Britain's very own James Corden.

Despite the quartet appearing to mislead viewers, a BGT spokesperson claimed that the group had every right to audition, stating: "Anyone can apply whether pro or amateur".

Responding to the news of Angara Contortionist's professionalism, one BGT viewer tweeted: "Any show that's run by @SimonCowell is fixed! You only have to audition to see for yourself! #BGT".

Britain's Got Talent continues this Saturday (13 May) at 8pm on ITV.
