Fuji Abound, do you have a link to where you are getting that extract of the ANO from?
The current ANO states
Instrument meteorological conditions rating (aeroplanes)
(1) Subject to paragraph (2), within the United Kingdom an instrument meteorological
conditions rating (aeroplanes) entitles the holder of a United Kingdom Private Pilot’s
Licence (Aeroplanes) to fly as pilot in command of an aeroplane without being subject
to the restrictions contained in paragraph (2)(c) or (f) of the privileges of the United
Kingdom Private Pilot’s Licence (Aeroplanes).
