Can you explain, please? Preferably without condescension. We are here to help each other understand. If I said something incorrectly, you could simply correct it, so that we can all learn.
Slobodan, there's a great deal of misinformation around, not only here but in our national media, who spout nonsense such as "parliament voted to outlaw no deal". The position, somewhat (but not hugely) simplifed, is this.
1. In March 2017 we gave notice, pursuant to Article 50 of the relevant treaty, that we intend to leave the EU. This followed the coming into force of the European Union (Notification of Withdrawal) Act 2017, permitting the PM to give it.
2. That notice has effect two years after it was given, unless we request, and all the other 27 countries unanimously agree, to defer the date of leaving.
3. We made such a request, and it was agreed, earlier this year. That is why the date, which was the end of March, is now the end of October.
4. The European Union (Withdrawal) (No. 2) Act 2019, known colloquially as the Benn Act after its originator, mandates the Prime Minister to request a further extension if no deal has been agreed.
5. It does not, and cannot, mandate a further extension, since such an extension requires the unanimous consent of the other 27.
6. Although the wording of Article 50 contains no such provision, the European Court of Justice has decided that a member state which has given notice to leave may withdraw that notice, provided it does so in good faith.
7. The only way in which Parliament can actually prevent our leaving on 31st October without a deal is to decide to revoke the notice given under Article 50 (a procedure almost universally, and wrongly, described as "revoking Article 50").
8. If nothing further is done, however, the default position is that we leave on 31st October.
That is why an election, which (depending on the way in which it was triggered) probably could not now take place before 31st October, would accomplish nothing much; we would probably have left by the time it took place.
"Probably"? Yes; because even if parliament is dissolved (which is wholly different from prorogued), the ministers of the Crown, including the PM, remain in office; and the obligation on the PM to request a further extension remains in force. There are various mutterings about mechanisms he might use to avoid the obligation, but none seems to have much validity.
I hope that clarifies matters a little.
