Outrageous to draw attention to empty speechifying (8)
I believe the answer is:
flagrant
'outrageous' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for flagrant that I've seen before include "Patent" , "Shocking" , "Blatant, outrageous" , "Barefaced" , "Openly outrageous" .)
