Trump's nemesis who'll produce denials, getting no support from 1,11,1? (6,7)
I believe the answer is:
stormy daniels
'trump's nemesis' is the definition.
(reference to Donald Trump)
'who'll produce denials getting no support from 1111?' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'denials' is 'daniels' which is present in the answer.
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is found within the answer.
This explanation may well be incorrect...
(Another definition for stormy daniels that I've seen is " Alleged source of personal gratification for Trump".)
