Explained: ICC Two-Tier Test System Proposal
The System proposes to group test playing nations into two with each group having a six teams.

London: The International Cricket Council (ICC) had decided during its annual general meeting in Singapore to explore the idea of a two-tier system in Test cricket, but what does it mean? Let's dive in to know more.
An eight-member working group, headed by ICC's new chief executive officer Sanjog Gupta, has been formed by cricket's governing body to explore the possibility of restructuring Test cricket.
Interestingly, the committee was set up during ICC's annual general meeting in Singapore under the all-Indian leadership of the chair, Jay Shah and Gupta, who was appointed as CEO earlier this month.
Currently, nine teams compete in the World Test Championship, but if the proposed two-tier system is implemented, the structure would shift to two divisions of six teams each, featuring a promotion and relegation mechanism.
CA and ECB discussed the two-tier concept last year. CA has been a key proponent, pushing for a model where Australia, England, and India face each other twice every three years, an increase from the current format of two series every four years.
Earlier, BCCI and other Asian test playing nations like the Sri Lanka opposed a 7 - 5 grouped two-tier proposal.
