JB Gill and Lauren Oakley have kicked off the Strictly Come Dancing final by getting a perfect score from the judges.

Viewers will find out on Saturday which of the four finalists – comedian Chris McCausland, Miranda actress Sarah Hadland, Love Island star Tasha Ghouri and Gill – will lift the glitterball trophy following a public vote.

Oakley and Gill were also told that them receiving 40 points was the 100th perfect 10 score given by judge Craig Revel Horwood.

The pair, who received help from Anton Du Beke during training this week were told by the judge they were “amazing”, as he also hailed himself as a teacher.

They recreated their quarter-final Viennese waltz to Let’s Go Fly A Kite from Mary Poppins as their judges pick.

“I know you’ve got three dances tonight, I would like to see that three times,” Du Beke said.

Judge Motsi Mabuse told the pair “that’s how you start a Strictly final”.

Oakley replaced Amy Dowden in early November after the Welsh dancer had to withdraw due to an injury.

Ghouri and dance partner Aljaz Skorjanec, and Hadland and Vito Coppola received 39 points from the judges after their routines.

Head judge Shirley Ballas praised Ghouri for getting “on top” of her emotion, and getting that to come through in the routine, while Du Beke said “are you the best dancer on Strictly Come Dancing? Quite possibly”.

McCausland also recreated his viral “blackout moment” for his couple’s choice routine to Instant Karma! (We All Shine On) by John Lennon.

Mabuse said “watching you dance is so, so incredible”, noting that he does not have the “orientation” to see that he is spinning partner Dianne Buswell around on his shoulders in the dark.

In the routine, McCausland can be seen placing his hands over Buswell’s eyes as the room faded to black, before the ballroom went dark and then the light comes back on with pyrotechnics flaring in the background.

They received a score of 38 points from the judges.
