While it is quite correct that the UK should not have to be signed up to taking part in a European super-state the renegotiation does not represent a big leap forward. With its’ opt outs that are not time limited the UK was already not further integrating with the EU. The change to accepting the de facto truth is not a big one. Allowing national parliaments a say may have a long term impact, but under the current mechanism it means almost nothing. It seems unlikely that 55% of member states national governments (which of course signed the deal) are ever going to lose in their parliaments. The bar is raised even higher by their being a time limit of 12 weeks.
