Camilla's sister, Annabel Elliot, has described King Charles and Queen Camilla's domestic life as a "constant battle".
The 75-year-old King and 77-year-old Queen, who spend their time at Clarence House in London, Highgrove House in Gloucestershire, and Birkhall in Scotland, are described as "polar opposites" in many parts of their everyday lives.
Elliot said that their varied preferences, including opposing ideas on the appropriate temperature for their home, sometimes result in humorous but regular "banter."
In Robert Hardman's biography, King Charles: New King. A new court. Annabel Elliot's The Inside Story depicts a strange domestic conflict between King Charles and Queen Camilla.
According to Elliot, the King loves a cool wind at his residence, whilst Queen Camilla prefers warm and comforting surroundings.
This mismatch of preferences sparks a debate about whether to keep the windows open, causing constant stress in their home.
As Elliot puts it, "There's a constant battle about it," emphasizing the royal couple's hilarious home contrasts.
