Tory MP Alan Duncan was foolish enough to say MPs live on "rations" and are "treated like shit". Of course, nobody forces him to stand, and given the competition every few years for the job, it would suggest that plenty of people are interested in the job.
Given Duncan is a millionaire from working in the energy sector, you'd have to wonder why he should care.
However, it does show a sad failure by those who get elected seeking to have power over others to recognise that they live a life well beyond the means of many of their constituents.
It is something MPs in New Zealand, on all sides of the house, may think carefully about.
