Dear All,
This is an interesting discussion.
I think the 'principal' of taking Politics out of Govt. (as I mentioned prev.), would take +/- 50% of the corruption out of National Govt. - it would at least remove the Party 'funding' & 'influencing' concept.
MP's would vote for any Cabinet, and Cabinet members would be able to be removed in just as swift a manner by MP's for lack of performance, as the MP's themselves by their Constituents.
As to landed gentry, well, look, there aren't that many in the 'real' category meaning as there were. There are the Westminsters', and Devonshires', and, to be honest, any landed gentry who can keep their Estates together these days must be pretty clued up one way and another.
Just a few ideas.
Regards, Bernard
