It is the issue that has divided the country and has also divided MPs in Kent and Medway.
As the Prime Minister continues to face pressure over her leadership, the county’s MPs - like the rest of the country - are split on whether the deal delivers what the government promised.
But only one has decided to join those who have called for a vote of confidence in the Prime Minister by submitting a formal letter to the chairman of the 1922 committee Graham Brady - the MP for Gravesham Adam Holloway.
As things stand the county is evenly balanced, with six saying they back the deal; six saying they do not and five yet to declare.
Here’s the breakdown:
Supporters of the deal:
Ashford MP Damian Green: Arguably Kent’s most Europhile MP and staunch defender of deal: “Absolutism is not going to work. All negotiations end in a compromise.”
Faversham and Mid Kent Helen Whately says she has not seen a better plan put forward: “Rather than re-running the referendum campaign, it’s time to focus on our future relationship with the EU.”
Maidstone MP Helen Grant: "The agreement is not perfect, but perfect was never on the table in such a complex negotiation. Furthermore, I don’t see any practical or workable alternative on offer.”
Tunbridge Wells MP Greg Clark: Says that a longer transition period would help small businesses and it is a good option to have.
North Thanet MP Sir Roger Gale: Says the deal is the best the UK can get at this stage.
Rochester and Strood MP Kelly Tolhurst: Voted remain in 2016 and said then she had not been convinced that it would be better to leave: “I don’t feel I have been presented with a coherent image of what that will look like.”
Gravesham MP Adam Holloway: Has called for vote of confidence in Theresa May: “You can not have someone leading a mission who does not believe in the mission. The country needs leadership."
Canterbury MP Rosie Duffield: “It is just about as catastrophic for Kent as it could be.”
Gillingham MP Rehman Chishti: Resigned as party vice-chairman in protest, saying the terms of the backstop amount to a "hybrid membership of the EU customs union and single market".
Folkestone and Hythe MP Damian Collins: Voted remain but says deal is flawed and is concerned at possible extension of transition period.
South Thanet MP Craig Mackinlay: A leading member of the ERG and says he won’t support the deal.
Dover MP Charlie Elphicke: "This proposal fails to honour the referendum mandate - we will not take back control of laws, money or trade. We would also pay £39bn with no clear sense of what we are getting in return."
Yet to decide or have not said
Sittingbourne and Sheppey MP Gordon Henderson: Unabashed Brexiteer. Undecided but minded to oppose the deal.
Dartford MP Gareth Johnson: Not yet said. A Brexiteer, supported Boris Johnson’s failed leadership bid.
Chatham and Aylesford MP Tracey Crouch: The former sports minister has not yet said.
Tonbridge and Malling MP Tom Tugendhat: Voted remain in the referendum but plans to read full document and take soundings from local association before deciding
Sevenoaks MP Michael Fallon: Yet to say.
