I WISH to respond to Colin S Jeffrey’s remarks about Prince Charles addressing the Queen as “mummy” (Letters, June 15). I have in my life known people young and old use this term. What is wrong with it?

I would also refer to his remarks about the Duke of Edinburgh “working a flanker”.

Mr Jeffrey probably does not know that during the war Lieutenant Philip, as he was then, served with distinction in the Navy at the Battle of Matapan. Also that Princess Elizabeth, as she was then, was called up at 18 and joined the ATS as a mechanic and dirtied her hands in the bowels of lorry engines and drove army lorries.
