Joined and made an effort to oust far right (4)
I believe the answer is:
tied
'joined' is the definition.
(I've seen this in another clue)
'made an effort to oust far right' is the wordplay.
I cannot really understand how this works, but
'an' could be 'i' (Roman numeral for one) and 'i' is found within the answer.
The remaining letters 'ted' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for tied that I've seen before include "Made bow" , "Drew; bound" , "Fastened with string" , "(Of pub) brewery-owned" , "Drawn" .)
