As one group, trash noble Conservative (2,4)

I believe the answer is:
en bloc
'as one' is the definition.
(French phrase meaning altogether)
'trash noble conservative' is the wordplay.
'trash' indicates anagramming the letters.
'conservative' becomes 'C' (UK political abbreviation).
'noble' with letters rearranged gives 'enblo'.
'enblo'+'c'='EN BLOC'
'group' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for en bloc that I've seen before include "As a group (French)" , "As a group (Fr.)" , "Wholesale, as one unit" , "All together, en masse" , "in wholesale fashion" .)
