President hasn't finished drink (4)

Ross

I believe the answer is:

chai

'drink' is the definition.

'president hasn't finished' is the wordplay.
'president' becomes 'chair' (synonyms).
'hasn't finished' means to remove the last letter.
'chair' with its last letter taken off is 'CHAI'.

(Other definitions for chai that I've seen before include "lady" , "Form of tea" .)

I've seen this clue in The Times.
