I have read your paper with interest. Brexit looks to be dragging interminably onward so, from a reviewer at the bottom of the globe, it is interesting to read how concerned English citizens are responding to the crisis. I applaud your attempts to engage actively with the process and attempt to encourage deliberative democracy.
As is my wont when reviewing papers, I have track changed comments into the attached. I have also, as requested by the editor, attached the rubric so you can see at a glance where I think you may need to do more work. [Update: seems to accept only one file so I will lodge a second comment with the rubric]. Of course, your choice to do so or not, bearing in mind the weight of all reviewers' feedback.
It seems to me that there are some quite significant claims made, for which I cannot yet see sufficient evidence to convince me of their validity. The evidence may be there but not yet strong enough, or you may be aware of actual case studies where success has been demonstrated. You also need to mention how you address the ethics of inclusion of video of the democracy cafe. Did participants know they were being videoed, and have they given approval for the video to be published?
I look forward to the next iteration of the paper, by which stage perhaps the Brexit situation may be resolved (I am ever the optimist!)
