Spectre of international consumed by anger (6)
I believe the answer is:
wraith
'spectre' is the definition.
('wraith' can be a synonym of 'spectre')
'international consumed by anger' is the wordplay.
'international' becomes 'i' (abbreviation eg in IMF).
'consumed by' is an insertion indicator.
'anger' becomes 'wrath' ('wrath' can be a synonym of 'anger').
'i' inserted within 'wrath' is 'WRAITH'.
'of' is the link.
(Other definitions for wraith that I've seen before include "'Ghost, spectre (6)'" , "Presence" , "Ghost-like apparition" , "Wrath I directed at spirit" , "Ghost or spectral appartition" .)
