The internal market bill aims to enforce compatible rules and regulations regarding trade in England, Scotland, Wales and Northern Ireland.
Some rules, for example around food safety or air quality, which were formerly set by EU agreements, will now be controlled by the devolved administrations or Westminster. The internal market bill insists that devolved administrations have to accept goods and services from all the nations of the UK – even if their standards differ locally.
This, says the government, is in part to ensure international traders have access to the UK as a whole, confident that standards and rules are consistent.
The Scottish government has criticised it as a Westminster “power grab”, and the Welsh government has expressed fears it will lead to a race to the bottom. If one of the countries that makes up the UK lowers their standards, over the importation of chlorinated chicken, for example, the other three nations will have to accept chlorinated chicken too.
It has become even more controversial because one of its main aims is to empower ministers to pass regulations even if they are contrary to the withdrawal agreement reached with the EU under the Northern Ireland protocol.
The text does not disguise its intention, stating that powers contained in the bill “have effect notwithstanding any relevant international or domestic law with which they may be incompatible or inconsistent”.
The bill passed its first hurdle in parliament by 77 votes, despite a rebellion by some Tory MPs.
