United States President Donald Trump has described the Iranian leadership as “seriously fractured” as he announced an extension to a ceasefire.

Trump said on Tuesday that the ceasefire would be extended to allow more time for negotiations and appeared to be suggesting that Iran’s leadership is in disarray.

He added that the US naval blockade on the Strait of Hormuz and Iranian ports would remain in place.

Three weeks ago, Trump claimed the US military campaign had succeeded in its goal of forcing a change in Iran’s government and the US was now dealing with “a whole new set of people” in charge of the country.

On April 11, Iran sent a delegation led by parliament Speaker Mohammad Bagher Ghalibaf to Pakistan’s capital, Islamabad, to begin talks with the US.

So is Iran’s government “fractured”? We take a look at the key Iranian stakeholders and power centres in Iran and how their approach to US negotiations may differ.

Who are the key figures in Iran, and are they ‘fractured’ over talks with the US?

Supreme Leader Mojtaba Khamenei

Khamenei is the second son of former Supreme Leader Ali Khamenei, who was killed in US-Israeli air strikes on Tehran on the first day of the war on February 28. Mojtaba Khamenei was selected as Iran’s new supreme leader on March 8, according to state media reports.

The 56-year old has never run for office or been elected but has for decades been a highly influential figure in the inner circle of his father, cultivating deep ties with the the Islamic Revolutionary Guard Corps (IRGC).

Observers said the younger Khamenei’s ascension is a clear sign that more hardline factions in Iran’s establishment have retained power and could indicate that the government has little desire to agree to a deal or negotiations with the US in the short term.

Since his ascension, however, Mojtaba Khamenei has not been seen in public. On March 13, US Secretary of Defense Pete Hegseth claimed Iran’s new supreme leader had been wounded in US-Israeli strikes.

An April 11, a Reuters news agency report that quoted three people close to the supreme leader’s inner circle said Khamenei was still recovering from severe facial and leg injuries suffered in the air strike that killed his father. The sources were quoted as saying he was taking part in meetings with senior officials through audioconferencing.

Al Jazeera could not independently verify these claims.

According to state media reports, Khamenei has been active in making decisions on the war.

In a message read on Iranian state TV on April 18, Khamenei warned that the Iranian navy was ready to inflict “new bitter defeats” on the US and Israel as tensions escalated in the Strait of Hormuz.

Parliamentary Speaker Mohammad Bagher Ghalibaf

Ghalibaf, 64, has served as Iran’s parliamentary speaker since 2020.

He was commander of the IRGC air force from 1997 to 2000. After that, he served as the country’s police chief. From 2005 to 2017, he was the mayor of Tehran.

Ghalibaf stood in elections for president in 2005, 2013, 2017 and 2024. He withdrew his bid for president before the election in 2017 when Hassan Rouhani won a second term.

Last month in the early days of the US-Israel war on Iran, it was suggested that Ghalibaf was the Trump administration’s “pick” to lead the country after the war ended. He has also been the main Iranian official leading negotiations with Washington since they began on April 11 in Pakistan.

In an overnight post on X on Tuesday, Ghalibaf wrote that Iran is “prepared to reveal new cards on the battlefield” after Trump threatened Tehran with “problems like they’ve never seen before” if the two-week ceasefire ended this week without a deal.

Ghalibaf expressed anger at Trump for “imposing a siege and violating the ceasefire”.

“We do not accept negotiations under the shadow of threats, and in the past two weeks, we have prepared to reveal new cards on the battlefield,” he said.

The ceasefire was supposed to have ended on Wednesday, but shortly before its expiration, Trump extended it until Iran “can come up with a unified proposal”.

Within Iran, however, Ghalibaf’s willingness to engage in negotiations with the US has been criticised by some people who have accused him of “betrayal”.

According to a report on Monday by the Iran International TV channel, some critics of Ghalibaf have said on social media platforms in Iran that the parliamentary speaker’s suggestion that peace talks with the US were progressing was “worrying”.

“There is no good in negotiation except harm,” one critic said.

But Ghalibaf has defended undertaking negotiations with the US. In a televised interview on Saturday, he said diplomacy does not mean “a withdrawal from Iran’s demands” but is a way to “consolidate military gains and translate them into political outcomes and lasting peace”.

Islamic Revolutionary Guard Corps

Iran’s military power structure is often described as opaque and complex.

The nation operates parallel armies, multiple intelligence services and layered command structures, all of which answer directly to the supreme leader, who serves as the commander in chief of all the armed forces.

The parallel armies comprise the Artesh, Iran’s regular army, which is responsible for territorial defence, defence of Iran’s airspace and conventional warfare, and the IRGC, whose role goes beyond defence and includes protecting Iran’s political structure.

The IRGC also controls Iran’s airspace and drone arsenal, which has become the backbone of Iran’s deterrence strategy against attacks by Israel and the US.

After the US and Israel struck Iran and killed Ali Khamenei, the IRGC promised revenge and launched what it called “the heaviest offensive operations in the history of the armed forces of the Islamic Republic against occupied lands [a reference to Israel] and the bases of American terrorists”. Since then, it has struck US military assets and infrastructure across the Gulf region.

Some experts said Iranian officials negotiating with the US are more closely aligned with the IRGC than other leaders and groups.

In an interview with Al Jazeera on March 25, Babak Vahdad, a political analyst specialising in Iran, noted that Iran’s appointment of Mohammad Bagher Zolghadr as secretary of Iran’s Supreme National Security Council suggested Iranian negotiations would become more tightly aligned with the IRGC’s priorities. Zolghadr is a former IRGC commander and has been secretary of the advisory Expediency Council since 2023.

But Javad Heiran-Nia, who directs the Persian Gulf Studies Group at the Center for Scientific Research and Middle East Strategic Studies in Iran, said a divide between the IRGC and Iran’s negotiating team was plain to see.

Iran has attacked three cargo ships in the Strait of Hormuz since Trump announced the ceasefire on April 6 and said the US naval blockade will remain.

“The attack on tankers during the ceasefire demonstrates the IRGC’s dominance over the diplomatic team and its disregard for their positions,” he told Al Jazeera.

Paydari Front

Heiran-Nia pointed to the role of the Paydari Front (Steadfastness Front), whose members are hardliners within Iran’s political structure who are deeply committed to preserving the original principles of the 1979 Islamic revolution and the absolute power of the supreme leader. This group, he said, has been using the negotiations to cement its position within the power structure and among its support base.

He added that the Paydari Front has also been questioning the negotiations.

“In Iran’s current political climate, various groups are trying to raise their weight, both within the power structure and in public opinion. Of course, the Paydari Front’s efforts are more meaningful in relation to their own support base rather than trying to influence other segments of society because their hardline approach holds no appeal for other social classes,” he said.

The influence this group could have over the progress of talks is debatable, however, he added.

“If a deal is reached, it will likely have a sovereign character. The establishment will impose its own narrative, and the IRGC will accept it. In the meantime, the hardliners will attack the administration of [President] Masoud Pezeshkian and Mohammad Bagher Ghalibaf over the deal. However, it is unlikely that this will spread to the decision-making body of the establishment,” he added.
