I don't see any difference between that and having a single class of MPs. It may, in fact, be an advantage to have one MP who represents the specific interests of the district and an MP who represents a wider interest. So basically I think that when people talk about this as a fact, and it is a fact that there are two different kinds of MPs, it's a fact but it's not a problem.
