How often have people commented that what Gibraltar needs is a government of the best brains? This is undoubtedly over-ambitious and impossible to achieve. Additionally there is no absolute measure of who would fit that description.
Those who say it are not so much meaning it literally, rather they are expressing frustration because they know that a few additional suitable persons might be encouraged to stand for election if the electoral system were to be changed. A change that would get away from the strict two party system delivered by the existing first past the post system.
Opponents to change argue that, absent a system that results in a clear governing majority, the consequence is weak and unstable government. This is shown, in practice, to be untrue. It is not what occurs in large countries that use proportional representation electoral systems already. What does happen is that it results in governments that are more representative and have greater consensus.
In Gibraltar where ideological political differences blur into insignificant and, on major issues, there is a large measure of agreement, the chances of weak and unstable government would be insignificant.
The reality is that an appropriate system of proportional representation would mean better and more diverse governance. More importantly it would improve democracy that additionally and, as argued in the blog immediately preceding this one, would enhance the sovereignty vested in the people of Gibraltar.
