Maufe asked, Is there a better system - ... than one person one vote etc?
How about abolishing political parties as an entity?
At a stroke you would avoid the need to fund party machines.
You would avoid the tactical voting.
You could vote for the man you think will represent the constituency best rather than against him because you don't want his party elected.
When the best are elected the ones who can secure the greatest support amongst those elected is asked to form a Government. The runner up becomes deputy.
The early US Presidential elections had the opposing candidate appointed as Vice President. That was certainly interesting and certainly fully representational.
