Although as I've said before I'm in favour of a 2nd ref with clearly defined outcomes I think the idea by Corbyn/Labour could be a little disingenuous.
In the detail it says a 'Labour-negotiated Brexit deal'.
1. I thought one of the big arguments was about how the government was sidelining everyone else, so surely it should be a cross-party negotiated deal.
2. Basically it's saying Brexit is called off until Labour has negotiated a deal with the EU, which is then put as the leave option in a referendum. Apart from the possibility that this could again potentially be misinterpreted by people as to the meaning of the wording (it would depend on what is negotiated and how it is written) it could potentially see Brexit being postponed indefinitely and in essence cancelled. If the EU and as many suspect many in Labour don't want to actually leave there is no incentive to actually negotiate a leaving deal to put forward to the public. Besides which even if they did there is still then the chance the public will vote remain.
But more than this it seems the options would likely be Remain or a number of the conventions being retained even if we leave, so those that do want a clean break haven't got an option at all. Now I know most of those that campaigned for Leave did say that a number of different options were available and various conventions would still be kept after Brexit, but this policy comes across to me as a get-out-of-Brexit-free card masquerading as a second referendum.
It would likely lead to a more palatable outcome for me given my beliefs, but it just seems rather disingenuous.
