Mojtaba Khamenei, the son of Iran's Ayatollah Ali Khamenei, who was killed in US-Israeli strikes, has been chosen as his successor.

Unlike his father, the 56-year-old has largely kept a low profile. He has never held government office, nor given public speeches or interviews, and only a limited number of photos and videos of him have ever been published.

But for years there have been rumours that he held considerable influence behind the scenes in Iran.

US diplomatic cables, which were published by WikiLeaks in the late 2000s, described him as "the power behind the robes" who was widely regarded as a "capable and forceful" figure within the regime, according to news agency AP.

US President Donald Trump said last week that Khamenei’s appointment as his father’s successor would be “unacceptable” to him.
