The Attorney General said the UK faces "disintegration" and that if it is adopted to choose international law, it will become "less prosperous and secure".
Richard Hermer launched a defense of international law and multilateral frameworks in his speech Thursday, "has been safe since 1945."
He denounced conservative leader Kemi Badenoch and her shadow attorney general David Wolfson, who accused the minister of strict compliance with international law and said: "Their arguments will provide success for (Vladimir) Putin if adopted."
"Their seductive simple narrative not only misunderstands the nature of our history and international law, but is reckless and dangerous, and will make us less prosperous and safe in a troubled world," he said.
Hermer is a human rights lawyer and former colleague of Keir Starmer, who was appointed chief legal officer of the government when labor took office last summer.
Earlier this year, he was attacked by the press among his past clients and also faced claims from internal critics that he is slowing down the government’s work.
He also faced criticism of the government's decision to agree to hand over the sovereignty of the Cagegos Islands to Mauritius after the International Court of Justice's advisory ruling.
Hermer held his annual security speech at the Royal United Services Institute to defend the government's international relations and accused Conservative critics of their "deeply" stance.
"Their analysis is realistic on the contrary - it is very undestined to know, perhaps fitting into the university debate chamber, but our enemies do not recognize the strategic benefits of frameworks based on international rules in the world."
"Let me be clear: I will not question sincere true beliefs for the time being, let alone pseudo-realist patriotism, but their arguments will provide success for Putin if they are adopted."
“In this dangerous world, it is illuminating to ask yourself: whether the international law framework fails, if our multilateral institutions fall, then Which one Bono? Who benefits? The answer is obvious - the success is our enemies. Obviously, Russia and other vicious state actors view the destruction of a legal-based framework as their core goal. ”
Helmer also accused the former Conservative government, especially Boris Johnson, who served as foreign minister and prime minister, but during this time undermined Britain's reputation on the world stage.
"No one can wisely think that Johnson's bombing has improved Britain's global position - people take us more seriously because of his sht's feet, allies or opponents are impressed by the doctrine of "cakeism" or believe that our reputation or reliability has improved our reputation or reliability through legislation that violates international law."
He argued: "It is a great British value to say that we want the world to be a better, safer, and more prosperous place. Between our views, there is no contradiction in our views, both a hard head and a warm heart."
Nevertheless, Hull defaults to that international law is “incomplete” and “must be criticized, reformed and improved.”
In the way some judges interpret the European Convention on Human Rights (ECHR), this would be seen as a criticism, Helmer said: “States that had agreed to the treaty for a period of time have not provided a broader interpretation of international rules, or no longer permitted to open international rules, or no longer adopt institutions to adopt blind or to take the status of blind people or to public literature among their member states.”
Ministers are reviewing how Article 8 of the Human Rights Act involves the ECHR of the domestic law to allow irregular migrants to remain in the UK.
