I don't think the leavers actually voted for opting out of any scientific cooperation or for damaging the economy, DMcG. I do think that many did not realise that the impact of their vote would have any such consequences because they were told that leaving would be easy and have no downsides. The remain campaign's warnings were, and still are, called "project fear". It is a testament to the duplicity of Farage, Johnson, Gove and co. that they managed to con so many and shame on the remainers for not going far enough to dispel such errant nonsense.

For that reason and many others the terms of the deal should be put to the country either in another referendum or a general election.
