With Boris Johnson set to leave for Brussels, where it seems most obstacles to a Brexit deal have been surmounted in time for a summit of EU leaders, the prime minister has work to do to convince MPs at home to back his plan. Northern Ireland's Democratic Unionist Party - which has helped prop up the minority Tory government since 2017 - is refusing to sign off on the PM's draft agreement. And a number of Tory Brexiteers have previously said their support for a deal is contingent on the DUP backing it too.
As our Reality Check explains, the key sticking points in negotiations have been around proposed new arrangements between Northern Ireland and the Irish Republic. Chief among them is finding a way to ensure ongoing political consent for an unprecedented dual customs system, which would see the land border acting as the legal frontier but, in practice, the Irish Sea being the point where checks take place. The DUP has released a statement this morning saying it cannot support the plans as they stand. Our political editor Laura Kuenssberg says issues between the UK, Ireland and the EU had otherwise been "pretty much ironed out". Meanwhile back in Parliament, she reminds us, "there are swathes of MPs ready to stand and fight" any such agreement.

Passengers on a British Airways flight which filled with smoke mid-air have told the BBC they are still experiencing breathing difficulties two months on. Among those flying to Valencia in August was Gayle Fitzpatrick, 40, from Glasgow, who says she now gets breathless walking uphill. "I don't smoke, I've never had any health concerns. So I know [it] must be directly attributable to that flight and whatever I inhaled," she says. BA says it "would never operate an aircraft" it believed "posed any health or safety risk" but cannot comment on the case until the Spanish air accident investigation is concluded.

Jewish MP Louise Ellman has quit Labour after 55 years, saying in a letter she is "deeply troubled" by the recent "growth of anti-Semitism" in the party. She fired a parting shot at leader Jeremy Corbyn, suggesting he is "not fit" to lead the country and that she "can no longer advocate voting Labour when it risks Corbyn becoming PM". Labour insists it is taking "robust action" to root out anti-Semitism. In July, Mr Corbyn proposed changes to Labour's complaints system to speed up the expulsion of members over anti-Semitism.

Papers offer a variety of takes on Boris Johnson's chances of securing a Brexit deal. The Daily Express says the prime minister is "tantalisingly near" while, for both the Times and Daily Mirror, his hopes balance "on a knife edge". The Daily Mail quotes Mr Johnson comparing the Brexit process to climbing Everest, saying the summit is near. But the Metro plays on the word, saying: "Summit's got to give". The death of Emmerdale actor Leah Bracknell, who played Zoe Tate, also features on several front pages.
