That's a good question as Eurocontrol recognises QNH as the correct
local barometric setting (they also state that it means Query: Newlyn
harbour). I thought the ICAO agreed with Eurocontrol on these things?

Actually, it's the other way round: Eurocontrol adheres to the ICAO
phraseology.


From The ICAO Manual of Radiotelephony (ICAO Document 9432)

Glossary:
QNH: Altimeter sub-scale setting to obtain elevation when on the ground

Example:
Fastair 345, descend to 4000 feet, QNH 1005, transition level 50, expect
ILS approach runway 24
