Orders of Precedence in The United Kingdom

British Royal Family

The sovereign, whether a king or queen, is first in the order of precedence. If the sovereign is male, then his wife, the queen consort, is first in the order of precedence for women. The reverse, however, is not always true. There is no solid law of precedence for a prince consort, so he is usually specially granted precedence above all other males by letters patent, or, on the other hand, may rank lower than the actual heir, his own son:

The order of precedence for male members of the royal family is:
The Sovereign	Whether male or female.
The Duke of Cornwall and of Rothesay	i.e. the Sovereign's eldest son.
The Sovereign's younger sons	Ordered according to their birth.
