Well said DH. There's no way article 50 can or should be triggered without a clear view of the longer term implications for British people of life post-Brussels. To do so without an agreed set of beliefs / principles would be the most ludicrous decision ever undertaken by any government ever. And to date, nobody, not one single soul has come up with an agenda (not even basic bullet points, ffs!) that needs to be adhered to / negotiated towards achieving as closely as possible. Until they do, there will be no progress.
