What makes you think that? The last thing Strictly needs is another scandal about the show being fixed.
While I suspect judges may be inconsistent with some contestants, going from showering with praise one week to tearing them apart the next, I would find it hard to believe the public vote has been rigged.
Having said that. If we are to go by popularity ⇔ votes, then those who have more social media presence will be at an advantage. Vicky has 5.5 million followers and more than 8 times as many as George Clarke on Instagram. It's not impossible for her never to land a dance off and eventually outvote everyone at the end.
