I interpreted Ms. May's comments on the paper a little differently. The way I read it is she was concerned that if she were the only Green Party member elected, she would only get perhaps one question a week. I think we're all satisfied that if there is only one member, they get up to one a week.
It certainly states that if the Green Party elects more than one member, they would have more than one a week, so I don't think there's a problem here.
