'favouring political organisation' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'that includes working party' is the wordplay.
'that' becomes 'ff' (I can't justify this - if you can you should give a lot more credence to this answer).
'includes' indicates putting letters inside.
'working' becomes 'on' (on can mean working or activated).
'party' becomes 'do' (do can informally mean a party).
'on'+'do'='ondo'
'ff' enclosing 'ondo' is 'FOND OF'.
