When Parliament took over from the King as the sovereign body.
Before that, the King would call his "Great Men of the Realm" and hear what they had to say about their regions, and the people within them. Any complaints of the people would be brought to the king. (Whether he did anything about them or not is another matter)
Now, though, Parliament spend so much time passing laws back and forth 15 times that the oldest function of the House, Representation, is left without any time. And since Parliament's agenda is ultimately controlled by Our Tony, he can keep it that way.
