Parliamentary Voting System and Constituencies Bill

I am very grateful to my noble friend, who has certainly done his homework and research very carefully indeed. Have I been advised correctly that the type of AV system that the Government propose should be used for elections to our House of Commons is found elsewhere in the world only in Papua New Guinea and Fiji? Has my noble friend, in the course of his research, found any lessons of more general application from those two laboratory experiments, which may be useful for us to think about as we consider an appropriate system for use in this country in the future?
