Spirit of Belfast radio presenter? (6)
I believe the answer is:
djinni
'spirit' is the definition.
(type of spirit in Islam)
'of belfast radio presenter?' is the wordplay.
I cannot quite understand how this works, but
'presenter?' could be 'dj' and 'dj' is present in the answer.
'of belfast' could be 'ni' (Belfast is in Northern Ireland) and 'ni' is found within the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
(Another definition for djinni that I've seen is " Arabian spirit".)
