Multinational blocked by current worker involving two factions (10)
I believe the answer is:
bipartisan
'involving two factions' is the definition.
(involving two political parties)
'multinational blocked by current worker' is the wordplay.
'multinational' becomes 'BP' (BP is a multinational oil company).
'blocked by' is an insertion indicator (I've seen this in other clues).
'current' becomes 'I' (symbol for electric current).
'worker' becomes 'artisan' (someone skilled in a particular craft).
'bp' placed around 'i' is 'bip'.
'bip'+'artisan'='BIPARTISAN'
(Other definitions for bipartisan that I've seen before include "Supported by both sides - aspirin tab (anag)" , "Cooperative" , "With both sides' agreement" , "using both sides" , "Like a coalition government" .)
