A proposal for free movement between Australia, New Zealand, Canada and the United Kingdom was proposed around three years ago. The agreement would be on the same sort of basis as the EU. London Mayor Boris Johnson, a great supporter of the proposal, pointed out that the people of Australia and the United Kingdom could hardly be more alike culturally and ethnically. Indeed, that is the central thrust of my just published book Prison Hulk to Redemption – all about the cultural foundations and continuities between the two blocks. This last week the proposal has had some more airing – much to my delight.
