The Lega Nazionale Professionisti (Italian for National League of Professionals), commonly known as Lega Calcio (Football League), was the governing body that ran the two highest football divisions in Italy, namely Serie A and Serie B, from 1946 to 2010. It has ceased to exist on 1 July 2010, following a split between Serie A and Serie B clubs, which led to the creation of two new leagues, the Lega Serie A and Lega Serie B respectively.
