Vulgar group seen around that guy in newspaper (10)
I believe the answer is:
broadsheet
'newspaper' is the definition.
(I've seen this before)
'vulgar group seen around that guy' is the wordplay.
'vulgar' becomes 'broad' (I am not sure about this - if you are sure you should believe this answer much more).
'group' becomes 'set' (both can mean a collection).
'seen around' is an insertion indicator.
'that guy' becomes 'he'.
'set' placed around 'he' is 'sheet'.
'broad'+'sheet'='BROADSHEET'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for broadsheet that I've seen before include "[OPPOSITE OF] Tabloid" , "Large-format newspaper" , "'Serious' newspaper" , "put to bed?" , "Something big that gets blanket coverage" .)
