Banker, upset, suppresses fury he's getting sacked (4)
I believe the answer is:
tees
'banker' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for tees that I've seen before include "Middlesbrough's river" , "Sides of Trent" , "used by golfers" , "English river" , "River on which Middlesbrough stands" .)
