It is understood that the Cabinet has specific roles:
- Share information about government departments and the progress of policies
- Coordinate between departments
- Resolve conflicts of policy
- Confirm government policy
Individual freedom of expression is required for effective debate but cabinet members are expected to present a united front to the outside world.
The Prime Minister (PM) has sole responsibility for appointing cabinet members and (s)he may expect their loyalty. The PM has the authority to set the agenda and chair cabinet meetings.
With Interactive Democracy I would expect the cabinet system to continue to exist in its present form. However, the agenda may be influenced by the demands of the public, expressed through Interactive Democracy, and ministers may have to take into account a much more powerful electorate.
