Agreed, and if you don't bother to vote you can't complain about the result.
The difference between the two is that as an MP you are only elected for a term, which can be no more than 5 years. Whereas some people seem to think that a referendum result is forever. which it isn't. It's only valid until you ask the question again. As we did before (with a similar question) in 1975.
Oh and you mean that Julia Hartley-Brewer who used to write for the Sunday Express. There's a surprise !
