Pub drama involving politician in French city (5,4)
I believe the answer is:
phnom penh
'city' is the definition.
(Phnom Penh is an example)
'pub drama involving politician in french' is the wordplay.
'pub' becomes 'ph' (abbreviation).
'drama' becomes 'noh' (Noh or No is a Japanese masked drama).
'involving' indicates putting letters inside.
'politician' becomes 'MP' (Member of Parliament).
'in french' becomes 'en' ('in' in French).
'mp'+'en'='mpen'
'noh' going around 'mpen' is 'nompenh'.
'ph'+'nompenh'='PHNOM PENH'
(Other definitions for phnom penh that I've seen before include "Cambodian capital" , "Capital of Cambodia" .)
