The threat of physical attacks by Iran on the UK now matches that of Russia, a watchdog has warned.
Parliamentâs intelligence and security committee said the threat from Iran has increased âsignificantlyâ since 2022 and wasâpersistentâ and âunpredictableâ, in a report published on Thursday.
Citing examples of 15 attempted murders or kidnappings of British nationals or UK residents by Iran, the committee said the physical threat posed by the country is âcomparable with the threat posed by Russiaâ.
Committee chairman Kevan Jones, the former Labour MP now known as Lord Beamish, warned that Iran has âa high appetite for risk when conducting offensive activityâ on foreign soil. âIts intelligence services are ferociously well resourced with significant areas of asymmetric strength,â he said.

Lord Beamish said the committee was particularly concerned about the rise in physical threats against dissidents and other opponents of the Iranian regime in the UK, with assassination used as âan instrument of state policyâ.
The report comes after hundreds of MPs and peers, including ex-Labour leader Lord Kinnock, called on Sir Keir Starmer to ban Iranâs Islamic Revolutionary Guard Corps (IRGC) after three Iranian men were charged with spying in London.
A letter, seen by The Independent, read: âAppeasing this faltering regime betrays democratic values, emboldens its repressive policies, and undermines global security as Tehran continues its nuclear ambitions and terrorism.â
Lord Beamishâs committee urged the government to consider whether it was âlegally possible and practicableâ to proscribe the IRGC as a terrorist organisation and make a full statement to parliament on the issue.
The report also warned that the nuclear threat from Iran had increased since the US pulled out of a key international agreement in 2018, arguing de-escalation âmust be a priorityâ.
The review from the nine-member committee, which scrutinises the work of Britainâs intelligence agencies, only covers the period up to August 2023, with its publication delayed by last yearâs election.
From the beginning of 2022 to the end of the committeeâs evidence-gathering, the report found there had been at least 15 attempts by Iran to murder or kidnap British nationals or UK residents.
The committee urged the government to make clear to Tehran that such attempts would âconstitute an attack on the UK and would receive the appropriate responseâ.
Lord Beamish added: âIran poses a wide-ranging, persistent and unpredictable threat to the UK, UK nationals and UK interests.
âAs the committee was told, Iran is there across the full spectrum of all the kinds of threats we have to be concerned with.â
Since August 2023, the international picture has changed with the outbreak of war following Hamasâs attack on Israel in October of that year.
The war has seen Iranian proxies such as Hamas and Hezbollah weakened, while last month the US and Israel carried out airstrikes on Iranian nuclear facilities over concerns Tehran was close to developing a nuclear weapon.
But the committee insisted that, despite these changes, its recommendations remained ârelevantâ.
The committee warned that, while Iran had neither developed a nuclear weapon nor decided to produce one by August 2023, it had taken steps towards that goal in recent years.
It found that Iran had been âbroadly compliantâ with the 2015 Joint Comprehensive Plan of Action (JCPOA) that limited its nuclear ambitions.
But since the US, under Donald Trump, withdrew from the deal in 2018, the threat of a nuclear Iran had increased, and Tehran âhad the capability to arm in a relatively short periodâ.
It also warned that the UK remained a target for Iranian espionage, which it found was ânarrower in scope and scaleâ and âless sophisticatedâ than the threat from Russia and China.
And while Iran had engaged in political interference activity, it said this had had âa negligible effectâ.
But the report cautioned that Iran-backed cultural and educational centres, such as the Islamic Centre of England, could be being used to âpromote violent and extremist ideologyâ.
The committee said it was also âessentialâ to âraise the resilience barâ on cybersecurity across the UK in the face of Iranâs willingness to carry out digital attacks.
Regarding the governmentâs response to the Iranian threat, the committee warned that policy had âsuffered from a focus on crisis managementâ over Iranâs nuclear programme and lacked âlonger-term thinkingâ.
It also criticised a âlack of Iran-specific expertiseâ, saying there was âseemingly no interest in building a future pipeline of specialistsâ.
One witness told the committee: âIf you have people running policy in the Foreign Office who donât speak a word of Persian, then that is a fat lot of good.â
The committee also noted that the UK had sanctioned 508 entities and 1,189 individuals relating to Iran by August 2023, but urged the government to reconsider whether sanctions âwill in practice deliver behavioural change or in fact unhelpfully push Iran towards Chinaâ.
But it welcomed the decision to place Iran in the âenhanced tierâ of the new Foreign Influence Registration Scheme, placing extra burdens on people acting on Tehranâs behalf in the UK.
