TV and papers ousting leader of party before fight (5,3)
I believe the answer is:
idiot box
'tv' is the definition.
(synonyms)
'papers ousting leader of party before fight' is the wordplay.
I cannot quite understand how this works, but
'papers' could be 'id' (identity papers) and 'id' is found within the answer.
'of' could be 'o' and 'o' is located in the answer.
'fight' could be 'box' (boxing is a kind of fighting) and 'box' is found within the answer.
The remaining letters 'it' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' is the link.
(Other definitions for idiot box that I've seen before include "TV set (US colloq.)" , "TV revealed" , "TV (slang)" , "tube" .)
