There is the odd one that cheats on expenses, absolutely/ However, rather than look at "how much" they claim in expenses, why not look at "what it is spent on"?
Their annual expenses and a chart showing what it went on can be found at
https://www.mps expenses.info/ (Thank you swear monitor - leave out the gap between mps and expenses) You go to the site, type in an MPs name and, voila, there's the info.
I give this info several times a year to folk posting on internet platforms/fora that xxxxxx the MP for Blabla North has claimed £147000 in expenses this year. At first sight it looks like the MP might be milking the system. Look at the figures and what the money has been used for and the vast majority of it will have gone on......
Rent for 2 offices. One in the constituency and one in London. Quite understandable and, IMO, acceptable.
Rent for a place to stay in London if their constituency isn't within a reasonable commute. Quite understandable and, IMO, acceptable.
Pay for staff in the 2 offices. Quite understandable and, IMO, acceptable.
Office supplies, gas, electric, water, rates etc for the 2 offices. Quite understandable and, IMO, acceptable.
Travelling expenses relevant to their work as an MP. Quite understandable and, IMO, acceptable.
Look at the facts and you will find that there is little to no "cheating" in expenses and that the vast majority of the claims are reasonable and justified.
Those that do claim for things they shouldn't ought to be removed from Parliament and by-election called in which they are no longer allowed to take part. They should also get charged with fraud.
