Glance at lad upset in disgrace (7)
I believe the answer is:
scandal
'disgrace' is the definition.
(scandal can mean disgraceful behaviour or news)
'glance at lad upset in' is the wordplay.
'glance at' becomes 'scan' (I've seen this in another clue).
'upset' indicates anagramming the letters.
'in' is an insertion indicator.
'lad' with letters rearranged gives 'dal'.
'scan' inserted inside 'dal' is 'SCANDAL'.
(Other definitions for scandal that I've seen before include "Rumour, gossip" , "Outrageous event" , "Shock" , "Shocking disgrace" , "Malicious gossip" .)
