In the general election campaign, none of the parties specifically mention the option to join the EU again post-Brexit.
However, in their manifestos, the Liberal Democrats, the Green Party and the Alliance Party all promise the option to have a second referendum to approve the Brexit deal, or reject it and remain in the EU afterall.
The Scottish National Party also promises a referendum for the Scottish people so they can take Scotland independent of the UK and effectively reject the Brexit deal that way if they wish.
And Sinn Fein want the final Brexit deal to require the approval of the Irish government and the Northern Ireland Executive.
Of course, all these options could halt Brexit and make the option to rejoin irrelevant.
On the eve of voting, how likely do you think it is that Brexit could still be stopped?
