Pressing one bloke once earlier (7)
I believe the answer is:
exigent
'pressing' is the definition.
('exigent' can be a synonym of 'pressing')
'one bloke once earlier' is the wordplay.
'one' becomes 'i' (Roman numeral).
'bloke' becomes 'gent' (I've seen this in other clues**).
'once' becomes 'ex'.
'earlier' is a charade indicator (letters next to each other).
'i'+'gent'='igent'
'igent' after 'ex' is 'EXIGENT'.
(Other definitions for exigent that I've seen before include "Demanding immediate attention" , "Urgent and taxing" , "Exacting, requiring much" , "Pressing; demanding" , "Pressing and urgent" .)
