Offered to look after English communist (8)
I believe the answer is:
tendered
'offered' is the definition.
('tender' can be a synonym of 'offer')
'look after english communist' is the wordplay.
'look after' becomes 'tend' (tending is a kind of looking after).
'english' becomes 'e' (abbreviation).
'communist' becomes 'red' (red is a kind of communist).
'tend'+'e'+'red'='TENDERED'
'to' is the link.
(Other definitions for tendered that I've seen before include "Offered as at auction" , "Offered a bid for a contract" , "Put in a bid for a contract" , "Made an offer" , "Made formal bid for contract" .)
