Indian leader upset our Henry a bit (5)
I believe the answer is:
nehru
'indian leader' is the definition.
(I've seen this before)
'upset our henry a bit' is the wordplay.
'upset' says the letters should be written backwards.
'a bit' says the answer is hidden in the clue (the answer is formed by a bit of the clue).
'urhen' can be found hidden inside 'our henry'.
'urhen' back-to-front is 'NEHRU'.
(Other definitions for nehru that I've seen before include "First Indian prime minister, 1947-64" , "First Indian PM" , "Asian statesman" , "Former Indian PM" , "Old statesman" .)
