They may arrange accommodation at large non-English events abroad (6,6)
I believe the answer is:
travel agents
'they may arrange accommodation' is the definition.
(travel agents may arrange holiday accommodation)
'at large non-english events abroad' is the wordplay.
'non' is a deletion indicator.
'english' becomes 'e' (abbreviation).
'abroad' indicates anagramming the letters.
'at'+'large'='atlarge'
'atlarge' with 'e' taken out is 'atlarg'.
'atlarg'+'events'='atlargevents'
'atlargevents' anagrammed gives 'TRAVEL AGENTS'.
(Another definition for travel agents that I've seen is " Trip organizers".)
