Upset unfortunately by delegation to university city up north (7)
I believe the answer is:
uppsala
'city up north' is the definition.
I can't tell whether this definition defines the answer.
'upset unfortunately by delegation to university' is the wordplay.
'upset' says the letters should be written backwards.
'unfortunately' becomes 'alas' ('alas' is used to express regret).
'by delegation' becomes 'pp' (I can't justify this - if you can you should believe this answer much more).
'to university' becomes 'U' (abbreviation for university).
'alas'+'pp'+'u'='alasppu'
'alasppu' backwards is 'UPPSALA'.
Can you help me to learn more?
(Other definitions for uppsala that I've seen before include "Would the Swedish city appal us?" , "City NW of Stockholm" , "Town with oldest Swedish university" , "City in Sweden" .)
