King is a Higher rank than Queen (slightly).....The Wife of a REIGNING King is entitled to be called Queen (Consort)......The Husband of a REIGNING Queen is called (Consort)...Hence Prince Phillip of Greece was known as HRH Prince Phillip, The Prince Consort, However he despised the title according to rumour, and was always known as HRH Prince Phillip, The Duke of Edinburgh.
Princess Annes Husband and her Ex Husband do not have the Title ""Prince"" because neither Mark Phillips nor Timothy Laurence are the Grandchildren of a Monarch.....(The requirement for the Title of Prince or Princess)
