What is Strictly Come Dancing?
Strictly Come Dancing is a BBC television dance competition in which celebrities are paired with professional dancers. First broadcast in 2004, it is one of the most popular shows in the UK and inspired Dancing with the Stars.
Each week, couples perform ballroom and Latin dances, such as the waltz, tango, cha-cha-cha and samba. Judges score the dances, and viewers vote.
The couple with the lowest combined score and votes may face a dance-off, and one couple leaves each week.

The show's format has been sold to many countries. In the United States, it is called Dancing with the Stars. Strictly is a highlight of the BBC's autumn schedule.
The final is usually held in December and attracts millions of viewers on BBC One.
