British legislating blasted for its bad language (12)
I believe the answer is:
billingsgate
'bad language' is the definition.
(thesaurus)
'british legislating blasted' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'blasted' is an anagram indicator.
'legislating' with letters rearranged gives 'illingsgate'.
'b'+'illingsgate'='BILLINGSGATE'
'for its' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for billingsgate that I've seen before include "Swearing" , "London fish market" .)
