Bars leaders of ICE, nauseating Nazi scumbags (4)
I believe the answer is:
inns
'bars' is the definition.
(I've seen this before)
'leaders of ice nauseating nazi scumbags' is the wordplay.
'leaders of' says to take the initial letters.
The initial letters of 'ice nauseating nazi scumbags' is 'INNS'.
(Other definitions for inns that I've seen before include "Country taverns" , "travellers' accommodation" , "Places to stay" , "Locals" , "Hotels" .)
