Platform providing power and widespread dislike (6)
I believe the answer is:
podium
'platform' is the definition.
(podium is a kind of platform)
'power and widespread dislike' is the wordplay.
'power' becomes 'p'.
'and' means one lot of letters go next to another.
'widespread dislike' becomes 'odium' (I've seen this before).
'p'+'odium'='PODIUM'
'providing' is the link.
(Other definitions for podium that I've seen before include "Speaker's platform" , "'Rostrum, dais (6)'" , "Lecturer's platform" , "Platform or pedestal" , "Stage" .)
