The direction of Bognor, think you? (5)
I believe the answer is:
north
'the direction' is the definition.
(north is a kind of direction)
'of bognor think you?' is the wordplay.
'of' indicates the answer is hidden within the clue.
'NORTH' can be found hidden inside 'bognor think you'.
(Other definitions for north that I've seen before include "Bridge position" , "Cardinal compass point" , "One looking for contract" , "Magnetic or true?" , "One of four bridge players" .)
