pretzels The HoC would decide PV options from 2 or 3 of the available ones:
WA / No Deal / No Brexit
For a PV to break the deadlock, it would probably need to be agreed by the HoC & the govt in advance that the result would be binding and automatically carried out
i.e. No further votes required, no GE until afterwards
The govt would afterwards be responsible for carrying out the result and getting any legislation through
No Deal is clear:
it is the option of greatest national harm
However, it is by far the most popular among Leavers;
the HoC / govt may not agree to omit it
ND Leavers' post-Brexit plan is to continue refusing the backstop in the belief that Ireland / the EU will eventually cave in
They refuse to believe all statements this won't happen, so we would actually have to go through and have it proven
Before the PV, we could try to agree with the EU that No Deal would bring an automatic A50 extension of say 2 years, not for negotiating any deals - that won't happen with ND - but just for both sides to complete prepping
They might, or might not agree.
In the end though, how the nation survives No Deal without the economy crashing and people suffering greatly is the govt's responsibility
