'monarch?' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'expert representation of' is the wordplay.
'expert' becomes 'authority' (authority is a kind of expert).
'representation of' becomes 'figure' (I am not sure about this - if you are sure you should believe this answer much more).
'authority'+'figure'='AUTHORITY FIGURE'
