it's not about how much they get. I think that's fine - and expenses for office costs is also fine.
I can even hack a (with a ceiling) amount for a 2nd "home" if their constituency is too far from London for a daily commute.
39 quid breakfasts? not so much - i would like the woman from our expenses department to do the expenses for MPs. 
What is absolutely appalling about this is:
a) his voting record on anything to do with welfare
b) the fact he said this on the very day the UC uplift was abolished.
it is tone-deaf at best.
He has to decide what WE can afford as taxpayers, to pay out in Universal Credit benefits to all claimants. So his salary is totally irrelevant.
Verginia, is that you?
