It is accurate. No deal brexit is the most likely outcome IMO.
Whatever next PM does, repeating what Theresa May has done and expecting something different is supposedly Einstein's characterisation of insanity, though several sources say Albert doesn't own that quote.
Extension becomes the most likely outcome (IMO) only if the next PM is brought down by no confidence within a couple of months. I suppose since that only needs a few tory defections it is not that remote.
Unfortunately extension doesn't solve anything it merely causes the can to be kicked down the road - again.
The EU have clearly stated that there won't be any changes to the deal, and that's dead in the water. Presumably if there was a change in government and another party was amenable to the four freedoms or was willing to be bound by rules that would enable a customs union then a different deal might be possible but it wouldn't be Labour (whose insistence on the ability to negotiate separate trade deals precludes a customs union) and the LibDems are a Remain party. IMO the only way there's a "deal Brexit" is if Labour decide to abstain on a vote on Theresa May's deal (or Boris' or Jeremy's but it'll be the same deal in floppy hat and glasses) as a last ditch way of preventing a no-deal Brexit - not a likely set of circumstances.
At the end of the extension period, we'd be back with the same three options as we've had since ever.....
- No Deal
- No Brexit
- A referendum to allow people to choose between No Deal and No Brexit
For the last two to be an option, it would require Parliament to vote in favour of them - which won't happen. Even if there is an extension, we'll likely end up with no-deal and why would the EU grant an extension under those circumstances ?
edited to add.....
Sorry, misread Francesca R's post and didn't clock that an extension would require a successful no confidence vote - which would give the EU a reason to grant an extension - a new UK government.
Having said that, I'm not sure that a General Election will solve any problems. If the Brexit Party is the party of government (or part of a coalition) then we're on for a no-deal

. Labour are still pro-Brexit (with deal aspirations at least as fantastical as an arch-Brexiteer's febrile imaginings) and anti second-referendum so we'll still be on course for a no deal and IMO the LibDems would have to poll 40%+ in order to get enough seats to be the lead partner in a coalition.
