I'd give them all at least £100k each. I want the best people seeing being an MP as a career and attracting the best brains, particularly where finances and welfare are concerned. The only way to get them to Westminster rather than the City is to pay the market rate. It's admirable that some choose to do it as their calling in life or want to serve the public, but for most it will be a career and in the trillions of public spending they control, it's a small price to pay. I wasn't even concerned about fiddling expenses (from either side of the house). It goes on in private circles too and again if those little fiddles mean we get the best of the best, then I'd happily turn a blind eye to it.
Do I think the emergency services and those who protect us deserve more too? Of course I do, but the budget only stretches so far and people also complain about higher taxes. We cant have it both ways and if a bigger pot is required, then we can only generate that through taxation. If it went direct, I'd happily pay another 1p in income tax, but then others would use that to petty point-score too.
