Disavowals from radical or a centrist (11)

I believe the answer is:

retractions

'disavowals' is the definition.
(retraction is a kind of disavowal)

'radical or a centrist' is the wordplay.
'radical' indicates an anagram.
'or'+'a'+'centrist'='oracentrist'
'oracentrist' with letters rearranged gives 'RETRACTIONS'.

'from' is the link.

I've seen this clue in The Times.
