SIR - I believe the ridiculous and appalling events at the Capitol Building, Washington DC, when Donald Trump encouraged an attack by his supporters to thwart the democratic process, are a good example of why we should keep our monarchy. We need someone for the politicians to look up to and be accountable to.

In the UK, the police and security services act on behalf of the Crown. In the US, they act for the President. So if the President himself becomes the problem, it makes things complicated. This is much less likely to happen here with the extra layer of the monarchy. And it helps when we have such a great Queen.
