Strictly Come Dancing 2017 final: everything you need to know

It's finally here. After weeks of glitz and glamour, the final of Series 15 of Strictly Come Dancing takes place this weekend.

Strictly aficionados will have no doubt been glued to the show throughout its latest run. But what if you're only in it for the extravagant and extended show that is the final?

Here's everything you need to know to get you clued up ahead of Saturday.

Who will be dancing in the final?

From 15 budding ballroom wannabees, whittled down to just four flamboyant finalists, months of gruelling dance-offs and routines have left us with the best of that initial batch of celebrities.

Alexandra Burke and Gorka Marquez, Joe McFadden and Katya Jones, Debbie McGee and Giovanni Pernice, and Gemma Atkinson and Aljaž Škorjanec are the couples who will by vying for the Strictly crown.

What are the songs and dances?

The final is certainly an event, and the winner of Strictly Come Dancing will be decided over two and a half hours of demanding dancing.

That time will be filled with each couple performing three different routines, a total of 12 dances overall.

Each of the couples will dance a Judges’ Pick (selected by the judging panel to challenge the pairs) their own Favourite Dance (the couple’s favourite routine from the series) and a Showdance.

The Judges' Picks and Showdances have been revealed ahead of the final - though what the couples are dancing to as their Favourite Dances won't be revealed until the final itself.
