It'll be interesting to see how they respond to Brexit given that Northern Ireland is a major sticking point. On Friday the Institute for Government published a report called "Getting Brexit Done. What happens now?" which says,
So at least that's one thing all sides of the assembly can agree on.The government will almost certainly be unable to implement the Northern Ireland Protocol by December 2020. This could result in the UK being taken to the European Court of Justice (ECJ) and cause practical and political disruption in Northern Ireland. The Protocol involves complex customs arrangements and regulatory and customs checks between Northern Ireland and Great Britain – but key details are yet to be decided by the Joint Committee established in the Withdrawal Agreement and not yet up and running. The deal has the support of no Northern Irish political parties and it looks almost impossible to complete the practical changes, for government and business, by the end of the year. Failure to comply with the Withdrawal Agreement could see the European Commission begin infringement proceedings and the UK ending up at the ECJ. [My emphasis, p3]
The Guardian has a summary of the report but the thing that strikes me most is how blunt it is with its language. There's no cautious optimism, it's words like "impossible" and "undeliverable". It sounds to me like people trying to ensure that they aren't the ones taking the fall when everything goes tits up.
