I think you make some useful points. It is probably unlikely that Ms Smith will be found to have broken the law, and will simply be found to have “made a mistake”. And in fact, maybe she hasn’t broken the law.
But the usefulness of the story will be in the fact that this shows just how much MPs are allowed to claim for, and given how this is an embarrasing situation, as opposed to maybe an illegal one, then more and more people will be less inclined to vote for her at the next election.
Also, don’t forget that her husband is being paid £40,000 a year as her assistant, so you would think that he would know the rules of what can and cannot be claimed for.
