Good morning! And welcome to Business Insider's live coverage of the meaningful vote.
We'll be providing minute-by-minute updates all day and through the night as Theresa May braces for herself for a potentially massive rejection of her Brexit deal.
Environment Secretarty and supporter of May's deal, Michael Gove, just told BBC Radio 4 that if MPs vote it down this evening, "in the words of Jon Snow, 'winter is coming'."
The leading Brexiteer was quoting the Games Of Thrones character, not the Channel 4 host.
May has warned that if Parliament does not accept her deal then chaos will be unleashed on the country, with a strong possibility of Brexit being cancelled altogether.
