UK PM Boris Johnson had set the October 15/16 EU Leaders Summit as the deadline but that has passed and talks plod on.
- The real deadline is the first week of November with a little, but not much, wiggle room. That would leave just under 2 months for legislation to drafted and passed, so any agreement could be implemented.
The European Parliament meet on November 23-26.
- It will have to ratify any deal agreed by EU leaders.
December 10-11 brings the next scheduled EU summit.
- If a deal hasn't been signed off by then this summit will see focus upon preparations for the UK to drop out of the EU in a chaotic manner
December 31 is the final day of the Brexit transition period. That deadline is set in stone.
- If the UK and EU have not agreed to a deal the UK exits on World Trade Organization terms.
Over four years of dithering has brought us to this point.
