The UK Government is planning new legislation that could allow it to adopt some future EU single market rules without a full Commons vote, using secondary legislation.
The move is part of wider efforts to align with new European regulations in areas such as food standards.
A Labour source told the BBC: "It will lower costs for businesses and get rid of the Brexit paperwork tax that adds to the cost of the weekly shop."
The government said the plans would help deliver a food and drink trade deal worth £5.1bn a year while cutting red tape for farmers, producers and businesses.
Opposition parties criticised the proposals. Shadow business secretary Andrew Griffith said Parliament would be "reduced to a spectator while Brussels sets the terms".
Nigel Farage said Reform would oppose the legislation "every step of the way", calling it "a backdoor attempt to drag Britain back under European Union control."
A UK-EU summit is expected later this year, with Keir Starmer saying it would be "more ambitious".
