A lot of successful countries use PR, so clearly it doesn’t lead to instability. In particular coalitions don’t always mean weak government. For example, Germany uses PR and has coalitions, yet is one of the strongest economies in the world and a significant power within Europe. Furthermore, Canada, India and the UK use FPTP and all have had coalitions. The UK coalition has so far proven to be both strong and radical. Michael Portillo, a former Conservative Minister of Defence has argued "They have been more radical on deficit reduction than say Margaret Thatcher was, but on top of doing that very difficult fiscal adjustment, they are also reformed schools, health, welfare, and pensions - areas where Margaret Thatcher didn't care to tackle."(Today, 2011)  The assumption that Proportional Representation leads to coalition also needs to be examined. Australia has for decades had strong single party government under the Alternative Vote.
