Boris Johnson arrived in Brussels on Thursday hailing his new agreement as a "reasonable, fair outcome".
The government says the new deal has 'ditched' the controversial backstop insurance policy for the Irish border.
European Commission president Jean-Claude Juncker says it means there's "no need for any kind of prolongation".
Gary Streeter, who represents South West Devon has begun reading the legal text saying it's the most important thing he's had to grapple with during his career in politics.
Speaking to Premier, he said: "I have been saying all the way through that I will support a sensible deal.
"I voted to remain, the people voted to leave, so we've got to leave but we've got to leave on a sensible basis.
"I think this looks like a sensible deal. I will certainly be supporting it and I think it's the right thing to do for the country."
The prime minister still needs MPs to support the deal in the Commons on Saturday - and currently Labour, the SNP, the Lib Dems and crucially the DUP say they won't.
While polls suggest the country still wants to leave, the nation remains deeply divided.
According to Streeter those divisions have even seeped into the parliamentary groups that he attends with other Christian MPs.
"A Bible study that I attend on a Tuesday morning, people (even within the same party) at the opposite end of the Brexit argument have sometimes found it uncomfortable to be in the same room as each other," he said.
"We've been able to overcome that by saying that our relationship in Christ is much more important than any one political issue, though this is an issue which is divided the nation.
"But there are some times when you have to be super sensitive to opposing views in the room and we've managed to overcome that."
