The meaning and origin of the expression: We are a grandmother

We are a grandmother

What's the origin of the phrase 'We are a grandmother'?

The use of the 'royal we' (the 'pluralis majestatis' or 'majestic plural') had previously been restricted, as one might expect, to royalty; for example, Queen Victoria's celebrated 'we are not amused'. Its use by a mere prime minister and Thatcher's imperious personal manner were the source of considerable disdain at the time. Thatcher's apparent conceit led to her being described as 'a legend in her own imagination' and to some linguistic jokes at her expense:

- Why is Margaret Thatcher like a pound coin?
- Because she is thick, brassy and thinks she's a sovereign.

Another quip came in the explanation from an aide as to why she had the nickname of 'Daggers' Thatcher. An interviewer asked, 'Is that because she has a reputation for stabbing colleagues in the back?' 'No, its because she's three stops past Barking.'
