Daisy, who wrote the series Victoria, said Carole, 64, is the ideal subject for a drama.
She told the Mirror: “People ask me if I’d like to write a drama about Harry and Meghan but I actually think I would like to write about Carole Middleton.
“Carole has an extraordinary story. She is a very, very interesting woman and she deserves a series."
Carole Middleton is married to Michael Middleton, and the couple currently live in Bucklebury, Berkshire.
Carole, whose family couldn't afford to send her to college, is an entrepreneur and self-made millionaire with her own business - Party Pieces - which has recently celebrated its 30th year.
