Editing Promotion and relegation (section)

===International sport===
Promotion and relegation is used in international sports leagues such as in [[Europe]], and many other parts of the world. It may be used in international sports tournaments. In tennis, the [[Davis Cup]] and [[Billie Jean King Cup]] have promotion and relegation, with a 'World Group' (split into two divisions in the Billie Jean King Cup) at the top and series of regional groups at a lower level. The World Groups in both use a [[knockout tournament]] format, with the first-round losers entering play-offs with winners from regional groups to avoid relegation. In international tournaments, this format allows teams from countries in which a sport is less well established to have competitive matches, while opening up the possibility of competing against higher ranked nations as a sport grows. Other international tournaments which employ promotion and relegation include the [[Ice Hockey World Championships]], [[Bandy World Championship (disambiguation)|Bandy World Championship]]s, [[Men's World Floorball Championship|Floorball World Championships]], the [[UEFA Nations League]], the [[CONCACAF Nations League]], the [[World Cricket League]] and the [[European Athletics Team Championships|European Team Championships]] in athletics.
