Shadow Business Secretary Andrew Griffith has declared that a future Conservative government would be willing to break international law to cancel the government's recent deal with the EU.
Speaking on GB News, Griffith described the agreement as a "terrible deal" and a "surrender Summit".
"It's a betrayal of Brexit, both in substance and in form," he said.
The comments come after the UK and EU struck landmark deals on defence, fishing and food standards yesterday in what has been described as the most substantial reset of relations since Brexit.

Griffith claimed the deal puts "the EU tomorrow, after this deal, in more control over our rules".
"It goes back to us being a rule taker, with the arbiter being the European Court of Justice," Griffith continued.

The Prime Minister has negotiated three major deals since entering No10GettyHe argued the deal provides "less control of our borders" by potentially allowing "millions of young people" from across Europe to enter the UK.
The shadow minister was particularly critical of the economic aspects, claiming any "ephemeral benefits that may or may not appear by 2040" would be "dwarfed by damaging things" like the Employment Rights bill.
He suggested the deal makes it "easier for the European Union to inter export their goods to compete with British jobs and British farmers".
Griffith insisted that "ultimately, the buck stops with the European Court of Justice and Brussels".

The fishing deal has been a particularly contentious element of the agreement. A new 12-year arrangement will allow full reciprocal access to waters until June 30, 2038, effectively rolling over existing terms that were due to expire next year.
This has sparked anger among British fishermen, with one Brixham fisherman telling ITV: "I voted to leave on the promises of what Mr Johnson told us. He went totally back on the word he gave us, and it looks like it has happened again now."
The Cornish Fish Producers' Organisation had recently called for a "fairer deal" as the previous post-Brexit fishing arrangements were set to expire in 2026.
Griffith vowed that a future Conservative government would take decisive action against the deal.
"We will repeal this bill. We will put it through the shredder," he stated.
He emphasised this would happen on "a busy first day of the next Conservative government" alongside repealing "taxes that have been punitive" and taking "back control of our courts and legal system".
The shadow minister was particularly critical of the 12-year timeframe of the fishing agreement, saying: "The idea he's going to try and bind this country and sell our fishing rights for 12 years, I think is way beyond anyone's contemplation."
"This is a bad deal. No if's, no buts," Griffith concluded.
