I feel like that's not actually the case. It would be the best position for remain voters at this point but I feel like it would be pain for zero gain. For as disastrous as Brexit is, there are at least some advantages to leaving.In absence of cancelling Brexit, this surely has got to be the most sensible option
But this approach would allow none of those advantages, whilst also throwing away all the benefits the UK currently accrues as a full member. It would be inefficient in every respect.
