Republicanism: Not for us.

I've just watched Janet Street-Porter on This Week. I couldn't believe how bitter she was towards Kate Middleton on her engagement to Prince William. Maybe she's a Republican, but why did she show so much malice towards Ms Middleton? Talking about her dieting as if it's a crime! If it is, you'd better lock me up.

I understand Republicanism, surely it doesn't make sense to have a hereditary head of state? Well, if you were to create a State from scratch you definitely would choose a different system. We do, however, have a thousand years of history entwined with our Monarchy and it's the most prominent constitutional Monarchy in the world due to the British Empire.

Consider the benefits. There's obviously tourism, the amount of money brought in by tourists more than pays for the price of Monarchy. They are good for morale, for instance the Queen Mother's resolve in World War II. For me, though, the biggest benefit is that the present Queen has been on the throne for nearly 50 years. She has had weekly audiences with 12 Prime Ministers. Imagine the amount of support and advice the Queen has been able to provide to the various PM's in that time. The Monarchy provides 'institutional memory'.

Then consider the alternatives. We would need a new Head of State. You could go for a ceremonial Head of State - like in Ireland. You'll get a failed or retired politician or a washed up celebrity. How about President Brown or President Jordan? No thanks. Instead you could go for a President with power, like in America where you often get deadlock with Congress.

On balance, I think our constitutionally Monarchy is much better than a possible Presidential system.

Congratulations to Prince William and Kate Middleton. It's nice to see a member of the Royal Family marry for love and that they have had a 'pretty normal' courtship. I wish them all the best.

Squiffy.
