Sir Nick has shown yet again that he absolutely doesn't get it. MP's should travel first class? First class travel is an outrageously priced , for the pampered few who are travelling at someone else's expense - in his case that's us taxpayers.
If he really said that there are 'a totally different type of people' on standard class trains it goes to show he's completely out of touch with the real world and real people. MPs are supposed to represent their constituents, not to be separated from them in some elitist haven. An MP should be glad to take the chance to make contact with the people who voted them into office - or who might vote for them next time.
I travel on trains a lot. Standard class, of course: the university can't afford to squander its money. And do you know, standard class arrives just as punctually (or otherwise) as first class? I get a lot of work done on trains - and so do many of the people round me. That's not an argument. I'm sure his views are not shared by the people of Macclesfield.
