Strictly Come Dancing songs and dances revealed ahead of the semi-final

The Strictly Come Dancing semi-final is upon us - and the four remaining couples have perfected two routines in a bid to win over the judges and the voting public.

Fresh from receiving the first 40 of the series, Karim Zeroual and Amy Dowden will perform an American smooth to Neil Diamond's Sweet Caroline and an Argentine tango to Libertango.

Meanwhile Kelvin Fletcher and Oti Mabuse will tackle the paso doble to the White Stripes' Seven Nation Army, along with a quickstep to The Lady Is A Tramp.

Emma Barton and Anton Du Beke will perform a cha cha and a waltz, while Chris Ramsey and Karen Hauer will tackle a Viennese Waltz and a rumba.

The couples will be hoping to avoid the dreaded dance off, which will see judges Shirley Ballas, Bruno Tonioli, Craig Revel Horwood and Motsi Mabuse decide which pair make it through.

Alex Scott and Neil Jones became the latest pair to leave the competition last week following a showdown with Chris and Karen.

At this stage in the series, five couples would usually be competing for four slots in the final, however due to Will Bayley's early departure due to a knee injury, this year just three couples will have a chance at lifting the glitter ball trophy.

Sunday night's results show will kick off with a special performance from the Strictly professionals with ballet superstar Carlos Acosta.
