Countdown to Brexit Day: Here are the key dates as the clock ticks down
We're on a countdown to October 31. But what other important dates should be in our Brexit diaries?
Finance Minister Paschal Donohoe will deliver his 'Brexit Budget'. It will be based on the assumption that the UK leaves in a disorderly fashion.
LATER THIS WEEK
Taoiseach Leo Varadkar is expected to meet with UK Prime Minister Boris Johnson to discuss his alternatives to the backstop. The meeting is unlikely to lead to a breakthrough.
The EU's General Affairs Council will meet in Luxembourg to lay the groundwork for the next summit of member state leaders. Tánaiste Simon Coveney will represent Ireland. It should be clear by then whether there is even the remotest possibility of a deal.
Leaders from across the EU will gather in Brussels to discuss the next steps. If there is a potential deal on the table, they will reach a unanimous conclusion on whether it is acceptable or not. It seems more likely that they will formally reject the UK proposals.
Under UK law, Prime Minister Boris Johnson is requested to seek a Brexit delay if he hasn't reached a deal by this date. Mr Johnson claims he will obey the law, but also says he will leave at Halloween no matter what.
This is Brexit Day - but it is impossible to tell whether the UK will actually leave or fresh talks will begin.
