In favour of attacking and advancing (11)

Ross

I believe the answer is:

propounding

'advancing' is the definition.
(propound can mean to advance or present)

'in favour of attacking' is the wordplay.
'in favour of' becomes 'pro' (being pro a particular cause).
'attacking' becomes 'pounding' (pound can mean to attack).
'pro'+'pounding'='PROPOUNDING'

'and' is the link.

(Another definition for propounding that I've seen is " Setting forth (an idea)".)

I've seen this clue in The Telegraph.
