Question

When a member of the royal family gets married, does the wedding have to be public, like charles and dianas?

Answer 1

No, the pomp given there was because Charles is the direct heir to the throne.

Answer 2

No, the queen's grandson got married today and it was a private ceremony.

Answer 3

Well, it seems your question is referring to the British Royal Family.

No, it doesn't have to be public but they are usually televised because they are wildly popular events.  Charles and Diana's wedding was watched by something like one billion people, wasn't it? It would be been a "disappointment" otherwise not to televise it. People are captivated by royalty at times.
