Sorry, you are MP for which contituency, jno? I have never heard of anyone stick up for an MP ever, and I did not know that they needed 2 homes at all. What are trains and travel expenses for anyway? If they live at Westminster then they won't need to travel there. I think the idea of an MPs only block of flats is brilliant. It could be owned by the Government, and if you lose your job, then you lose your flat, simple.
Mind you to give them their due the MP for Shrewsbury (sorry I forget the name now, help me out all you Salopians) did once run the London Marathon, and thus went up in my estimation. I wonder how many of them also give blood. Probably none, as they are all bloodsucking parasites.
