Parliamentary Voting System and Constituencies Bill

I am grateful to my noble friend, my near neighbour, for giving way. Could he resolve this dilemma? He mentioned that there was the early unpopularity of coalition Governments at the same time as there was popularity for a change to a more proportional system. A more proportional system will more than likely—I put it no stronger than that—lead to coalition Governments. How does he square the circle of the popularity of the voting system with the unpopularity of the product it produces?
