Smug head office tour in health resort (6-4-4)

Ross

I believe the answer is:

holier-than-thou

'smug' is the definition.
(holier-than-thou can mean smug or sanctimonious)

'head office tour in health resort' is the wordplay.
'head office' becomes 'HO'.
'resort' indicates anagramming the letters.
'tour'+'in'+'health'='tourinhealth'
'tourinhealth' with letters rearranged gives 'lierthanthou'.
'ho'+'lierthanthou'='HOLIER-THAN-THOU'

(Other definitions for holier-than-thou that I've seen before include "Sanctimonious" , "Self-righteous" .)

I've seen this clue in The Times.
