I take your point WannaBe, but look at why they were allowed to make these claims.
all following quotes from this source
"All MPs had to sign a declaration with every claim to the effect that "I confirm that I incurred these costs wholly, exclusively and necessarily to enable me to stay overnight away from my only or main home for the purpose of performing my duties as a Member of Parliament"."
" ... the UK's Parliament has worked for centuries on the basis of MPs being "honourable members" so in most cases the fees office was, perhaps not surprisingly, unlikely to challenge an MP if they had given their signed word that the claim was legitimate."
"Sir Thomas, in his letter, says he could not find any rules covering how much could be claimed for gardening and cleaning so had had to judge what he thought were fair limits."
"It seems that Sir Thomas has decided that MPs should not have been able to claim more than £1,000 a year for gardening at their second home and more than £2,000 for cleaning - including laundry and dry cleaning."
Now I have to say I don't see having the garden of your second home done as completely neccessary to doing the job of MP. And how the hell does dry-cleaning relate to the second home rather than the person wearing the dry-cleaned clothes?
I'd also take issue with the £400/month food allowance, which I don't think is being asked to be repaid. I can see the need for two store-cupboards (condiments, herbs etc) and I don't expect the MP to personally pay for the tea and biscuits offered to constituents at surgeries etc, but £400 is taking the piss (and my MP has claimed for it most months).
I see this less as a moving the goalposts and more of a give it back and we won't take this matter any further. I think the MPs should consider themselves to have been let off lightly.
