The UK government has scrapped a promised completion of a post-Brexit "bonfire" of remaining EU-era laws by the end of the year.
Business Secretary Kemi Badenoch said they would now revoke around 600 laws under their planned legislation, rather than the 4,000 pledged.
She acknowledged there are "risks of legal uncertainty" by automatically scrapping the laws by the end of the year in a sunset clause in the Retained EU Law Bill.
In a written statement to MPs, Ms Badenoch said ministers will amend the Bill to replace the current sunset with a list of 600 EU laws to be revoked by the end of the year.
"We will still fully take back control of our laws and end the supremacy and special status of retained EU law by the end of 2023," she said.
She said a further 500 pieces of retained EU legislation would be revoked by other means.
Jacob Rees-Mogg has accused Prime Minister Rishi Sunak of having broken his promise to revoke EU laws.
In a statement to the PA news agency, the former Conservative business secretary said: "The written ministerial statement breaks the Prime Minister's clear promise to review or appeal all EU laws in his first hundred days.
"Instead, he has decided to keep nearly 90% of retained EU law.
"This is an admission of administrative failure, an inability of Whitehall to do the necessary work and an incapability of ministers to push this through their own departments.
"Regrettably, 'the blob' has triumphed and the Prime Minister has abandoned his promise."
