Iran’s exiled prince has warned Western powers against appeasing the Islamic Republic's new president, saying the Iranian people would view it as a betrayal of their struggle for freedom.

"The people of Iran will view any attempts to appease this new lackey (Masoud Pezeshkian) as a treacherous offense to their ongoing movement for liberation and a shameful abdication of moral leadership," Prince Reza Pahlavi said in a post on his X account on Saturday.

Masoud Pezeshkian won the July 5th runoff election with a turnout of less than 50%. In his first post-election speech, he thanked Supreme Leader Ali Khamenei, saying, "If it wasn't for him, I don't think my name would have easily come out of these (ballot) boxes."

Prince Reza Pahlavi referred to the election as a "fraudulent" attempt to legitimize a dictatorship, highlighting the Iranian nation’s rejection of the process.

He said Khamenei’s choice of Pezeshkian as the president and "chief functionary" would not save the Islamic Republic from its "inevitable" collapse and the Iranian people's "certain" victory.

Pahlavi also praised Iranian people for boycotting the election, calling it a "historic" display of national unity and solidarity and a "watershed moment" in the Iranian nation's movement.

He noted that this was the largest display of "nonviolent, civil resistance" against the Islamic Republic in 45 years and emphasized that this is just the beginning of their path to national liberation.

The first round of Iran's snap presidential election saw a voter turnout of 39.92%, the lowest in the history of the Islamic Republic. In the runoff votes, the official figures show a 10-percent rise in the number of voters, but still over 50 percent of eligible voters boycotted the election.
