Please help: how to make a big improvement in the alignment of political parties’ incentives with the public interest?

I am interested in these questions:

1) What incentives drive good/bad behaviour for UK political parties?

2) How could they be changed (legal and non-legal) to align interests of existing parties better with the public interest?

3) If one were setting up a new party from scratch what principles could be established in order to align the party’s interests with the public interest much more effectively than is now the case anywhere in the world, and how could one attract candidates very different to those who now dominate Parliament (cleverer, quantitative problem-solving skills, experience in managing complex organisations etc)?

4) Is there a good case for banning political parties (as sometimes was attempted in ancient Greece), how to do it, what would replace them, why would this be better etc (I assume this is a bad and/or impractical idea but it’s worth asking why)?

5) In what ways do existing or plausible technologies affect these old questions?

What are the best things written on these problems?

What are the best examples around the world of how people have made big improvements?

Assume that financial resources are effectively unlimited for the entity trying to make these changes, let me worry about things like ‘would the public buy it’ etc – focus on policy not communication/PR advice.

The more specific the better: an ideal bit of help would be detailed draft legislation. I don’t expect anybody to produce this, but just to show what I mean…

The overall problem is: how to make government performance dramatically, quantifiably, and sustainably better?
