The Monarchy and the Constitution

According to the blog Tartan Hero the nationalists of Catalunya in Spain are calling for the abolition of the Spanish monarchy. As in Britain constitutional power rests with the government and not with the monarchy. Canada, Australia and New Zealand share Britain's monarchy and the majority of people see no good reason to change that. The nationalists' quarrel here in the U.K. lies not with the monarchy but with the government and the British constitution as established in England. The government therefore should undertake a complete evaluation of the constitution in the light of its contemporary relevance.
