Why is UK publishing a ‘command paper’ on Northern Ireland protocol?

Trading arrangements continue to be a significant flashpoint in relations with Dublin and Brussels

Just seven months after it came into force, the Northern Ireland protocol is proving once again a significant flashpoint in the UK's relations with Dublin and Brussels.

On Wednesday, the UK published a command paper" on the protocol. Some will see it as an attempt to tear up the agreement Boris Johnson struck in 2019, others will see it as a serious attempt to fix a deal they argue was flawed from the beginning but signed to help the British prime minister to get Brexit done, as he had promised.
