Ok thats a good source
Not just that - it's the law and entirely logical. NB all those whingers who complain about how boring and irrelevant Air Law is.
albeit not very well worded for an aerodrome that has a right hand circuit
Why? If a right hand circuit is in force, it directly implies that ground signals should indicate this - unless there is an ATC unit, of course.
So if the local ATC authorise a right base join to a left hand circuit its for sure ok.
Of course - that's what the law says. But note - ATC - not FIS or AGCS.
