The Cambridge Union Society's debates are at least as good as those at its Oxford equivalent, which it preceded in foundation by eight years (Cambridge Union 1815; Oxford Union 1823 obviously in imitation).   I debated in the Cambridge Union frequently 60 years ago in my student days, & was also a member of one of its administrative committees. So I don't quite know what Jim on about at 0258 pm; but that's nothing new: he does rather tend to make his facts up, rather than ascertaining what is correct -- Cambridge Union Society & Oxford Union Society can both be easily accessed on Wikipedia.
