When the UK leaves the EU, a bill will be introduced that will make it easier to amend or repeal EU rules that were carried over into British law.
On the second anniversary of Britain leaving the EU, Downing Street said the measures would make it easier to cut 1 billion red tape for British businesses.
It did not say what provisions would be included in the bill to speed up reforms, or how it calculated that businesses would save 1 billion through the cutting of red tape.
Ministers have so far made slow progress in identifying and altering previous EU rules and regulations that are derived from the UK's membership of the bloc. Last year, they changed the rules around the hours HGV drivers were allowed to work to deal with supply change problems. They have promised to revoke EU regulations that ban shops from selling goods by imperial measurements only.
Some changes could be problematic with the terms of the trade deal struck with Brussels. The UK must make sure that any changes to domestic law do not give UK firms an unfair advantage over EU competitors or face potential trade tariffs.
According to Downing Street, changing or scrapping regulations would take several years because of a long-winded alteration process.
The bill would allow changes to be made by ministers through a process that normally passes through parliament without a vote, and is not stated by No 10 that primary legislation was needed for many changes, even if minor and technical ones.
Boris Johnson wrote in today's Daily Mail: "We have all kinds of reasons to celebrate our new freedoms two years after we left the EU. We have taken back control of our money, our borders and our laws. We have done more than 60 free trade deals. He said it is time to put aside the old divisions. Two years on, it is time to abandon the punitive and zerosum approach. As we develop the post-Brexit agenda of freedom, it will be great for Britain and good for the whole of Europe.
