Relieved everyone still in Scotland departs (7)
I believe the answer is:
allayed
'relieved' is the definition.
('allay' can be a synonym of 'relieve')
'everyone still in scotland departs' is the wordplay.
'everyone' becomes 'all' (all people).
'still in scotland' becomes 'aye' (Scottish dialect term meaning still or always).
'departs' becomes 'd' (common abbreviation e.g. train timetables).
'all'+'aye'+'d'='ALLAYED'
(Other definitions for allayed that I've seen before include "Put at rest, say suspicions" , "Assuaged, relieved" , "Soothed or diminished, say fears" , "'Diminished or put at rest, fear perhaps (7)'" , "Eased" .)
