Good point. The role of Prime Minister has crept into presidential status that was never intended when our parliamentary system was created. The chancellor used to be the one with the power, because they held the purse strings. The PM was more of a chairman for the cabinet, which was composed of independent MP's in the days before party politics took its stranglehold and created career politicians and single-party cabinets. What is the point of electing a parliamentary representative for your constituency if they have no voice in parliament, and no power to effect real change? Parliament shouldn't be a single voice for the party with the most MP's.
