The PMs office is split into 4 departments:
- Private Office
- Political Office
- Press Office
- Policy Directorate
Under the Interactive Democracy (ID) system I would expect that this structure would continue. Much of the governments agenda would be set through the ID system and I would imagine that the Political Office and the Policy Directorate would work closely together to encourage votes from party members, in order to create a majority that would push the desired policies through the public ID system. Us voters would decide if we liked them or not.
