For consultants and their clients still struggling with Brexit nitty-gritty (and who isn't) I offer you the peerless Chris Grey, Professor of Organization Studies at Royal Holloway, University of London, and The Brexit Blog.
Learned, measured, well-connected, detailed — everything so much Brexit commentary is not.
You can follow him on Twitter @chrisgreybrexit.
Worth your time.
If only the government and its advisers did too.
