Control deliveries in centre of Bognor (6)
I believe the answer is:
govern
'control' is the definition.
(governing is a kind of controlling)
'deliveries in centre of bognor' is the wordplay.
'deliveries' becomes 'over' (a cricket over consists of six deliveries).
'in' indicates putting letters inside.
'centre of' indicates the central letters.
The central letters of 'bognor' are 'gn'.
'over' placed into 'gn' is 'GOVERN'.
(Other definitions for govern that I've seen before include "Control and direct the affairs of" , "Rule with authority, perhaps a country" , "Manage - control" , "Control, determine" , "Run" .)
