Iranian President Hassan Rowhani said Monday that neither he nor his government will bend under pressure from political hardliners.
"None of our ministers will bow to pressure or step back," Rowhani said during a meeting with members of the Iranian Medical Council.
Rowhani's reformist camp won parliamentary elections in February and defeated the hardliners who were critical of the nuclear deal reached with the international community.
The hardliners say that Rowhani has little to show for more than a year after the nuclear deal, which was supposed to ease the country's economic crisis with the lifting of sanctions.
With nine months to go until the presidential election, political hardliners are using this issue to campaign against Rowhani and prevent his re-election in May.
Rowhani responded strongly to insults directed at the Iranian team that struck the historic nuclear deal with world powers in July 2015.
These criticisms are neither factual nor fair, according to Rowhani.
"This team worked hard, day and night, for 30 months to reach this agreement," he said on state television. "They do not deserve these vulgar insults."
Rowhani risks losing the election to his predecessor Mahmoud Ahmadinejad, who is supported by the hardliners.
