Matter-of-fact shareholder's meeting welcomed by idiot in charge (9)
I believe the answer is:
pragmatic
'matter-of-fact' is the definition.
(a pragmatic approach is a matter-of-fact one)
'shareholder's meeting welcomed by idiot in charge' is the wordplay.
'shareholder's meeting' becomes 'AGM' (annual general meeting).
'welcomed by' means one lot of letters goes inside another (letters welcomed inside).
'idiot' becomes 'prat' (both can mean a stupid person).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'agm' placed within 'prat' is 'pragmat'.
'pragmat'+'ic'='PRAGMATIC'
(Other definitions for pragmatic that I've seen before include "Realistic" , "for best results?" , "Practical" , "Dealing with things practically rather than theoretically" , "Matter-of-fact" .)
