I expected another extension. There have been so many extensions already, I feel conditioned to expect they'll just keep doing it. It feels like noone on either side actually wants Brexit to happen, but they've politicked each other into a corner, and they're all too proud to back down. It will be a shock when a deadline hits and they finally don't extend it.

Only 2nd extension. It's more about "democratic rule and negotiations is difficult". If it was XVIII century they would have simply leave & do the rest with an Armada.

Third, actually.

Granted 22 March 2019, 10 April 2019, and today.

Or fourth, perhaps.

This all started after the referendum, when David Cameron decided not to send in the A50 letter on the next working day. The EU-27 first mumbled politely that was okay, then mumbled equally politely that the letter had better be sent before a year had passed. And indeed it was signed and sent shortly before a year had passed.

There was nothing formal about that, but if you want to count deadlines then that one may be the first. Or not, IMO it depends on why you're counting.
