It bears repeating that responsibility for the Brexit deal rests with the government that negotiated it, signed it and recommended it to Parliament and the country as a great outcome. /1

If the government are happy with the deal, think it’s working well and that any downsides are justifiable, they should say so and defend it. /2

If however the govt thinks problems are emerging with the deal they agreed, they should recognise that and work with the EU & member states to address them. That need not be a matter of shame & would be more constructive than misrepresenting the deal and blaming everyone else.
