Interesting fact:

The poor Queen features quite a lot in British slang! She also has her own slang names such as ‘Liz’, ‘Lizzie’ and, for some reason, people sometimes call her ‘Brenda’. Apparently, this is the fault of satire magazine ‘Private Eye’ which also calls Prince Philip ‘Brian’ and Prince Charles ‘Keith’ – I imagine her Majesty is not amused…
