About what I, and seemingly many others, had in mind. But additionally, IMHO:

... and have done so for a minimum period before the current election. Say 5 or 10 years. Their main residence should also be in the constituency and this MUST be their main residence for all taxable purposes! MPs expenses policy MUST align with HMRC policies (though expenses is a whole subject on its own after the recent/continuing sagas! Suffice it to say that expense policy should mirror, say, the average private company expense policy).

I think contributions should only be possible from registered voters in each constituency, NO business contributions, and only up to a maximum (say £25) per year. With c. 100K people per constituency that should be ample. It'd get prospective MPs back to the doorsteps arguing their points and really finding out what their constituents want from them.

Agreed. And their would have to be some way to force them to honour their manifesto commitments, though maybe the recall sanction would be enough.
Also, make it that ALL votes in the HoC are votes of conscience and not whipped, though with the above I believe that there would be many more independent MPs so this would be less of a problem. And no bill to be voted on if it can't be explained in simple terms to the 'man in the street'. So no way of even voting for, say, an EU treaty that you haven't even read .... not that I'd mention any names there ......
But above all MPs need to understand that they represent US in the HoC so the 'recall' option should sharpen their minds considerably as would the 'referism' approach.
