The United Kingdom is a monarchy ruled by Queen Elizabeth (the mother of Andrew), even though the British people go far out of their way to pretend that's not the case. It's why Boris Johnson had to meet with the queen about forming a new government. Why is she involved at all? It's because she rules the United Kingdom in fact. Andrew's family rules Britain (for what, 1200 years? [1]), that's quite relevant to the context. The political structure of the United Kingdom goes very far out of its way to look after and protect the royal family (their rulers).

Shall we pretend that the family that has ruled Britain for 1200 years has no political power? Har har.

Every country in Europe that still regressively clings to a monarchy (and there are a lot of them) goes out of its way to pretend - because it's so comically backwards - that their monarchy is only a figurehead / ceremonial and has no real role. In fact they're all back up dictatorships waiting in the wings if there's ever enough political chaos to prompt the people to turn to that, and that happens every time historically.
