Icc approves test championship one day league
I think there may be some confusion here!
The ICC (International Cricket Council) has not approved a "Test Championship One Day League". The ICC has, however, introduced a new format called the ICC World Test Championship (WTC), which is a two-year cycle of Test matches between the top nine teams in the ICC Test rankings.
The WTC is a league-style competition, where teams play each other in a series of Test matches, with the top two teams in the standings meeting in a final to determine the champion. The WTC is designed to provide a more structured and competitive format for Test cricket, which has been criticized for being too fragmented and lacking a clear structure.
So, to clarify, there is no "Test Championship One Day League" approved by the ICC, but rather the ICC World Test Championship, which is a league-style competition featuring Test matches between the top teams in the world.
