I'm John Batson with my colleague Gregory Copley, defense and foreign affairs, the author of a new book, Noble State, about the superiority of a constitutional monarchy compared to a state that must combine the head of state and the head of government in one person. It gets confusing.

We see this because the presidentialism of the U.S. is a prime example of how wearing two hats

can be confusing. Whereas in Britain, Mother Britain, King Charles is the state. The government is

Sir Kerr Starrmer who's struggling. King Charles, however,

has problems that all previous heads of state have had when they're kings, which is second sons.

And Gregory, we don't much talk the gossip, and Harry, the second son of King Charles, is a troubled person.

Fine. Andrew, however, King Charles's brother

acts malevolent. I can't tell. I can't read these things. But reading the Roman Empire, for example,

in the late 2nd century AD, there was an emperoraris, who left his will that the kingdom should

be divided between his two sons, Caracalla and Gata.

Caracalla had a solution for sharing, which was to murder his brother.

That's not available to Charles.

So, given that you have recommended a constitutional monarchy, is Andrew a threat to the

realm, his bad acting? No, I don't think so. We have to bear in mind that from the days of

Caracalla to today, the position of monarchs around the world has changed dramatically. They tend to be heads of state,

not heads of government. So they have authority, they have prestige, they have the ability to

embody the principles of the society, but they are not the ones in charge of the mechanisms of state craft in many respects.

So the second sons, whilst they might be jealous, they might be directionless because they believe they've been robbed of their birthright,

they're not really in a position to threaten the throne other than to make things embarrassing

for the king or queen who's regnant.

And that, by the way, is definitely a problem for King Charles to face with Andrew, particularly,

but also with his son, Prince Harry.
