The Rugby Football League has announced that the Super League will be a 12-team competition from 2015.

The clubs have agreed to a change to the structure of the current format, which is contested between 14 clubs.

Prior to 2009, the Super League was made up of 12 clubs, but the RFL decided to award two additional licences and abolish promotion to and relegation from the competition.

Currently, the top eight sides at the end of league season go into the playoffs in a bid to reach the annual Grand Final.
