Parliamentary Voting System and Constituencies Bill

I just want some clarity. The way in which the noble Lord put it when asked the question appeared to state an analytical conclusion by the Electoral Commission—that it thinks that the options route is alien to how it has been done in the past and would lead to a different sort of campaign. That all sounds like analysis. Did I understand the noble Lord to say that there had been focus groups and testing by the Electoral Commission? If there were such focus groups and testing, are the results of that published? If so, where can we find it—and if it is not, could he publish it?
