I think a system where multiple parties exist in a single govgenmet house works well, it doesnt give the elcted party full control but does five them a majority acvcording to their support. This also give a better prospective when it comes to elections, anyone that followes politics knows how the respective parties act and which views they have throughout the term a govenment has in office, it also means that the opposition parties can place pressure on the prime minister to get things to happen. The biggest flaw in the UK system is that Labour could win next years election on a minority vote of 35% whereas a 45% majority is needed by the conservities to take office.
