CANZUK, the idea of Canada, Australia, New Zealand and the United Kingdom forming a trade, foreign affairs and defence alliance...
It's an interesting idea. However, it should be extended to the entirety of the Commonwealth Realms.
If the idea were to bear fruition... It could lead to a 2 - tier Commonwealth of Nations.
The Commonwealth Realms, could become a single entity within the Commonwealth of Nation's, aligned on trade, foreign and defence affairs.
The wider Commonwealth, could be part of the trade policy, forming a superpower block with an estimated GDP of 10.4 trillion.
The Commonwealth of Nations, is an existing structure with potential that's waiting to be unleashed. It would be a beacon for stability and promote good relations among it's members.
BREXIT isn't about isolation, it's about going global!
