Bogan leader to erupt, getting relegated rank (7)
I believe the answer is:
lowbrow
'bogan leader to erupt' is the definition.
I can't tell whether this defines the answer.
'relegated rank' is the wordplay.
'relegated' becomes 'lowb' (I can't explain this - if you can you should give a lot more credence to this answer).
'rank' becomes 'Row' (I've seen this in another clue).
'lowb'+'row'='LOWBROW'
'getting' is the link.
Can you help me to learn more?
(Other definitions for lowbrow that I've seen before include "Lacking intellectual tastes" , "not requiring much intelligence" , "Hard mass in wood, shore bird" , "Mass-market" , "Unsophisticated" .)
