here. The other is our Prince Charles! (See image.)
Neither the Queen nor any of the politicians - Blair is mentioned by name - survived the Change. Thus, King Charles, now married to Queen Hallgerda, heads a royalist government.
Also of interest: our viewpoint character, the former SAS man, John Hordle (a reference to John Hord?), is six foot seven inches. That is big. Recently in town I was passed by a big black guy who was head and shoulders above me. When I tapped him on the shoulder and (politely) enquired as to his height, he replied, with a very pleased smile, "Six seven!" So, throughout this novel, I will bear in mind how tall Hordle is. And I will be interested to find out whether King Charles comes on stage.
In another timeline, Poul Anderson's Terran Empire has a Mayor Palatine of Britain and we wonder whether that Mayor is a member of the House of Windsor.
