Belfast doctor maybe is involved with my opposition to local development (8)

I believe the answer is:

nimbyism

'opposition to local development' is the definition.
(nimby means 'not in my back yard')

'belfast doctor maybe is involved with my' is the wordplay.
'belfast' becomes 'NI' (Belfast is the capital of Northern Ireland).
'doctor maybe' becomes 'MB' (Bachelor of Medicine).
'involved with' is an anagram indicator (involved can mean confusing or complex).
'is' anagrammed with 'my' gives 'yism'.
'ni'+'mb'+'yism'='NIMBYISM'

I've seen this clue in The Times.
