Jim. not a problem.
D the G. you ask a lot and it deserves far more than my usual 3 liner.
There are many changes that could be made that in my opinion would improve our present system.
1) control lobbying ( How to do this with any degree of success escapes me)
2)Change the qualifications for becoming an MP.
( I would prefer to see a minimum age of say mid 40's.)
3) pay each mp 150k/year.
4) On leaving office pay continues for 10 years but no speeches, no    jumping through revolving doors, no politicking of any description backed by mandatory sanction of jail.
5)Change the legal status of corporations so that greed is tempered by a small degree of morality
6)Curb the undue influence of the SE of England over policies and investment.
7) Certain categories of voting in Parliament to be free votes.
   ( I leave it to others to categorize)
8) Minimum attendance levels of MP's for any vote to be valid.(50+%)

I am sure others could suggest many other options. Perhaps the thread should migrate.
