I definitely think it's a fine line, but you're never going to be behind those closed doors to know what that conversation is. You're speculating that perhaps the conversation sometimes veers left and veers right and doesn't stay centred. It's a fair speculation. It's your job as an opposition MP to ask those questions, but I'm not so sure that you look at this....
Prime ministers and ministers have advisers, and those advisers have expertise in the areas in which advice is needed. They have that expertise because they have histories in those areas or current engagements in those areas.
The question is, do they stay on point? Do they stay centred on the actual project?
