Commonwealth Games Defunct?

Why do we have the Commonwealth Games?

Australia (who is the big dog behind a little fence in this situation) want to become a republic, England hasn’t made any meaningful steps to reinforce the Commonwealth in 30+ years and countries like New Zealand and it Pacific neighbors have very little significant connections with the Motherland other than carrying the Union Jack and abiding by ceremonial traditions. Oh and there is the legal system bit as well but we'll exclude that for the sake of this blog.

Attendance at the Games is not flash hot especially in early stages of heats etc. Would there be any benefit from finishing the Commonwealth Games to let Athletes and the world audience focus solely on the Olympic Games? I think there would as it would make the Olympics that much more elite and special.

That a look at this forum from the Australian newspaper the Age. The Commonwealth Games Forum
