Absolutely not. Listen to any talk "down the pub" about the monarchy. It is extremely unlikely you'll hear anything positive. (Unless it's New Year's Eve when everyone has a shared "proud to be British" sentiment.)
Honest question: Can you name a public figure that people down the pub do say positive things about?
Stephen Fry.
Nigel Farage (typically, ugh).
David Attenborough
The Actor who plays Mrs Brown in Mrs Browns Boys.
The British monarchy as individuals (excluding Charles)
I think we go to some different pubs.
Ah, yes. The trendy hip pubs with attached microbrewery.
