Extra juicy shocker about leaders of trade and industry (7)
I believe the answer is:
tastier
'extra juicy' is the definition.
'shocker about leaders of trade and industry' is the wordplay.
'shocker' becomes 'taser' (I've seen this before).
'about' indicates putting letters inside.
'leaders of' indicates taking the first letters.
'and' means one lot of letters go next to another.
'industry' becomes 'i' (this could be a standard abbreviation of which I'm unaware).
The initial letter of 'trade' is 't'.
't'+'i'='ti'
'taser' going around 'ti' is 'TASTIER'.
(Other definitions for tastier that I've seen before include "Having a more pleasant flavour" , "More appetising" , "More palatable" , "More attractive" , "More flavoursome" .)
