International cricket chiefs have backed an expansion of the Twenty20 format, agreeing three extra matches per major country should be played in years when a world championship is staged.
At the moment, each senior nation is limited to an annual maximum of 12 matches in the game's shortest format.
It was also decided at the ICC Chief Executives' Committee meeting that the 2014 World Twenty20, to be played in Bangladesh, should be increased to 16 teams.
