Iran has dismissed accusations from British officials that it poses a threat to the United Kingdom's national security, calling the claims unfounded and misleading.

The rejection comes as the UK government moves to classify Iran as a top-tier foreign influence risk under a new registration scheme aimed at countering external threats.

Foreign Ministry spokesperson Esmail Baghaei issued a statement rejecting the allegations, asserting that they are not only false but also a deliberate attempt to divert public attention.

He criticized the UK for its history of interference in Iranian affairs and accused it of continuing to support groups opposed to the Islamic Republic.

The spokesman dismissed the recent allegations by British officials as baseless and false, arguing that they were intended to deflect public attention. He also accused the UK of a longstanding pattern of counterproductive interventions in Iran and of providing ongoing support to anti-Iranian terrorist groups.

Baghaei further advised British officials to abandon their confrontational policies against Iran and to stop instigating and inciting terrorism.

The UK's Security Minister, Dan Jarvis, recently announced that Iran would be placed in the highest tier of the Foreign Influence Registration Scheme, requiring individuals working on behalf of Tehran to register their activities or face imprisonment.

British intelligence agencies claim that Iran-linked operations have increased, alleging that multiple plots targeting dissidents and posing threats to national security have been thwarted in recent months. The UK has also raised concerns over Iran's alleged use of criminal networks to target opposition figures in Britain.

Tehran has repeatedly condemned Western nations for what it describes as interference in its internal affairs, particularly their support for anti-Iranian groups.
