Strictly Come Dancing returned for its fourth series on 7 October 2006. Bruce Forsyth and Tess Daly returned to co-present the main show on BBC One, while Claudia Winkleman returned to present the spin-off show Strictly Come Dancing: It Takes Two on BBC Two. Len Goodman, Arlene Phillips, Craig Revel Horwood, and Bruno Tonioli returned as judges. Mark Ramprakash and Karen Hardy were announced as the winners on 23 December, while England rugby player Matt Dawson and Lilia Kopylova finished in second place.

Format

The couples dance each week in a live show. The judges score each performance out of ten. The couples are then ranked according to the judges' scores and given points according to their rank, with the lowest scored couple receiving one point, and the highest scored couple receiving the most points (the maximum number of points available depends on the number of couples remaining in the competition). The public are also invited to vote for their favourite couples, and the couples are ranked again according to the number of votes they receive, again receiving points; the couple with the fewest votes receiving one point, and the couple with the most votes receiving the most points. The points for judges' score and public vote are then added together, and the two couples with the fewest points are placed in the bottom two. If two couples have equal points, the points from the public vote are given precedence.

Couples

This season featured fourteen celebrity contestants.
