Kremlin chiefs will supply Iran with components capable of making deadly nuclear weapons, Britain has confirmed.
Russia will help Tehran in exchange for hundreds of Kamikaze drones currently being fired at Ukrainian targets.
Defence Secretary Ben Wallace Russian intends to “provide Iran with advanced military components" in exchange for "kamikaze drones.”
The Iran nuke fears re-emerged as Belarus despot Alexander Lukashenko admitted he and Vladimir Putin are the “most toxic people on this planet."
The pair met amid fears Russia wants to relaunch an attack on Kyiv via Belarus
Last week the Daily Mirror was first to highlight alarm over Russia wanting to help Iran develop its nuclear programme in exchange for weapons.
This followed claims by former FBI terror expert Ali Soufan that Russia may enable Tehran’s secretive nuclear programme.
In a statement on Ukraine Wallace told the Commons: "We must stop their reckless shelling of nuclear facilities. We must hold their enablers to account.
"Iran has become one of Russia top military backers.
“In return for having supplied more than 300 kamikaze drones, Russia now intends to provide Iran with advanced military components, undermining both Middle East and international security.
"We must expose that deal. In fact I have just now."
In our exclusive we revealed how both pariah countries are under massive sanctions and struggle to raise currency to buy weapons and components.
It is believed they have struck secret deals - Shahel-136 missiles for nuke components, putting Iran’s old enemy Israel under threat.
Soufan had written: “Both countries are subject to sweeping US and European sanctions and the extent to which Russia is able to provide Iran with hard currency payments for the drone production agreement is unclear.
“As an alternative Iranian leaders may seek additional Russian assistance to boost their nuclear programme.
“Maintaining Russia as a partner may also help in circumventing sanctions that hinder Iran’s ability to acquire components and other goods for its advanced weapons programmes.”
Under a 2015 deal called the Joint Comprehensive Plan of Action Iran agreed not to forward its nuke programme for 15 years in exchange for a relaxing of crippling sanctions.
But three years later then President Trump pulled out of the deal, signed by Britain, Russia, Germany, the US and France.
On Tuesday Ukrainian President Volodymyr Zelensky visited the embattled city of Bakhmut, the recent focus of some of the most intense fighting of Russia's war.
The eastern city is the scene of "fierce battles" between Ukraine's defenders and Russia's invading forces.
Earlier this month, Mr Zelensky said Russia's efforts to conquer Bakhmut had turned the eastern Ukrainian city into ruins.
He said: "The occupiers actually destroyed Bakhmut, another Donbas city that the Russian army turned into burnt ruins.”
And there are growing fears Russia intends to reignite its bid to launch a ground attack on Kyiv, via Belarus.
Lukashenko said of him and Putin: “You know, the two of us are co-aggressors. The most harmful [and] toxic people on this planet.
"And if someone today thinks of tearing us [apart], of forcing us apart…..”
At the same time Ukrainian head of the Armed Forces Serhiy Nayev warned weapons have been moved from Russia to Belarus, escalating fears the Kremlin will launch another land invasion towards Kyiv.
He said: "We closely monitor the weapons transferred from Russia . . . the level of military threat is gradually increasing."
