A total of 150 delegates representing the 105 full, associate and affiliate members of the International Cricket Council (ICC) will begin a series of groundbreaking discussions when its Annual Conference gets underway in Edinburgh tomorrow.

The week-long event, which concludes on July 2, is seen as one of the most important gathering of cricketing officials in recent history, with a number of key items on the agenda at the Caledonian Astora Hotel.

The competition structure of the ICC is likely to be a hot topic as members will debate whether to create a two-tier international Test league.

Currently, there is no existing league system in place for the Test format, considered by many as the pinnacle of the sport, but plans are on the table to implement a brand-new tournament from 2019 onwards.

It would involve seven times in the top division and five in the bottom, with promotion and relegation between each tier.

The Test league could be played either every two or four years, and teams would still be able to stage regular Series outside of the competition.

“There’s a general realisation now that, if we’re going to keep Test cricket going well into the future, we can’t just say it’s going to survive on its own,” ICC chief executive David Richardson said earlier this month.

“Unless we can give some meaning to these series beyond the rankings and a trophy, then interest in Test cricket will continue to waver.

“The same applies if we allow uncompetitive Test cricket to take place too often.”

The ICC are also likely to rubber-stamp an additional World Twenty20 tournament in 2018, with the competition then held on a biennial basis rather than its current quadrennial status.

The next event wasn't due to be staged until 2020 but there could now be one in two years and also in 2022.

The move comes due to the volumes of revenue generated by this year’s edition in India, where the West Indies beat England in a thrilling final.

ICC chairman Shashank Manohar has been behind an idea aimed at reducing the powers of the “Big Three” cricketing nations - India, England and Australia - after they were granted more influence and larger shares of revenue in 2014, which is set to feature prominently during the week.

It is thought the changes made two years ago will be scrapped, though this has to receive the full backing of the ICC Council when it holds a full meeting on Thursday (June 30).

The Indian Express has reported that the Board of Control for Cricket in India are expected to be fully behind former chairman Manohar's proposal.
