Liga MX has suspended promotion and relegation for the next five years, president Enrique Bonilla announced.

A vote was held via a video meeting between the 18 Liga MX owners on Friday, with promotion and relegation from and to the league suspended for the next five seasons as part of an agreement with the 12 teams in Ascenso MX.

Bonilla confirmed the 12 second-division clubs will receive guaranteed yearly payments of almost $1million from the top flight during that period, with Ascenso MX to promote the inclusion of younger Mexican players in squads.
The 2020 Ascenso MX season has also been cancelled, with no champion crowned, due to the COVID-19 crisis.
