This page lists the official World Champions – Professional Latin of the World Dance Council (WDC).
 The championships are authorized and organized under the auspices of the WDC, and held annually in the last quarter of each year.
 The competition comprises five dances: rumba, samba, paso doble, cha-cha-cha and jive, as defined in ballroom dancing terms.
Gaynor Fairweather is a British professional ballroom dancer.
 She and her partner, Donnie Burns, were 14-time Professional World Latin Dance Champions and 11 times Professional International Latin American Dance Champions.
 This is by some way the record number of wins in both these top competitions.
 On their retirement from competition dancing they were both appointed Members of the Order of the British Empire (MBE) for services to the performing arts.
In latin dancing, the jive is a dance style that originated in the United States from African-Americans in the early 1930s.
 It was popularized in 1934 by Cab Calloway.
 It is a lively and uninhibited variation of the Jitterbug, a form of Swing dance.
 Glenn Miller introduced his own jive dance in 1938 with the song "Doin' the Jive" which never caught on.
Michael Malitowski is a ballroom dancer, a former World Latin Dance Champion with his partner Joanna Leunis.
 Michael (christened "Michał") was born 28 May 1980, in Zielona Góra, Poland.
 His partnership with Leunis has, since 2002, resulted in a string of victories: in 2008 and 2009 they won the World Professional Latin title, and in 2012 they won first place in Latin dance at the Blackpool Dance Festival.
 This is the prestigious Open British Championships held every year in Blackpool, England.

The Lockers (originally named The Campbell Lockers) were a dance group formed by Toni Basil and Don "Campbellock" Campbell in 1971.
 Active throughout the 1970s, they were pioneers of street dance.
 Don Campbell is the founder of the locking dance style, and originally, Locking was called The Campbellock - a style that was based on the dance and song that Don Campbell created.
 Toni Basil met Campbell at a club in 1971 and together they formed The Lockers as a dance group.
 Toni Basil also served as The Lockers' manager, and was responsible for staging the act.
 All the dancers contributed steps and choreography with their unique and individual styles.
 By 1975 they were "Dancing their way to stardom" on their own.
 Individual members' contributions (as soloist performers) to the dance style and group image coupled with their unique presentation in staging and concept broke down many barriers.
 It has been said on the reality dance competition "So You Think You Can Dance" that "The Lockers' emergence on the dance scene changed the face of dance not only for street dancers but for dance in general and has made street dance a true American art form."
Joanna Leunis, born 22 May 1981 in Rocourt, Liège, Belgium, is a professional Latin ballroom dancer.
 With Michael Malitowski, she is a former professional World Latin Dance Champion and the current International Latin American Dance Champion.
