Who is Mojtaba Khamenei, the newly appointed supreme leader of Iran?

In 1999, Mojtaba traveled to Qom, a sacred city regarded as a significant hub of Shia theology, to further his religious education. It is worth mentioning that he had not donned clerical attire until then, and the reasons behind his choice to enroll in a seminary at the age of 30 are not clear, as typically individuals pursue this path at a younger age.
