A key deadline is looming for Brexit Britain. The British government has until Monday, December 4th, to finalise its offer on three key issues: the Irish border, a financial settlement and European citizens rights. The EU's chief Brexit negotiator, Michel Barnier, said clarity on the British offer had to be provided in advance of the EU leaders' summit in December. The EU's 27 members will then decide whether "sufficient progress" has been made to move the talks on to the next phase about a future trading relationship. So has Britain's offer gone far enough? What sticking points remain? And would Britain walk away from the talks if its position is rejected? Owen Bennett Jones and a panel of guest discuss the state of the Brexit negotiations. What will it take for them to advance - and what happens if they do not? (Photo of EU/UK flag pin by Dan Kitwood/Getty Images)
