Good name kept by parliament led by person with honour (8)
I believe the answer is:
obedient
'good' is the definition.
('obedient' is associated in meaning with 'good')
'name kept by parliament led by person with honour' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'kept by' indicates putting letters inside.
'parliament' becomes 'diet' (I've seen this before).
'led by' says to put letters next to each other.
'person with honour' becomes 'obe' (Order of the British Empire).
'n' placed inside 'diet' is 'dient'.
'dient' after 'obe' is 'OBEDIENT'.
(Other definitions for obedient that I've seen before include "Passive" , "Docile" , "Doing what one is told, compliant" , "Like monk" , "Doing as one's told" .)
