Burhan Borak was sentenced to 12 years and 3 months in jail over seven posts on social media in 2014, T24 said. The judge rejected to request for postponement of punishment. With this, every social media post received 1 year and 9 months.
The sentence is "the severest punishment" regarding all insulting the Turkish president cases, according to Borak's lawyer.
"Such punishments are not surprising in a country where the judiciary is not independent. We will appeal to a higher court about the given sentence. I hope justice will prevail," Borak said.
In Turkey, insulting the president carries a jail sentence of between one and four years, according to the Turkish Penal Code.
The Turkish government has been using social media posts, cartoons, news reports and other articles as evidence for charging people with insulting the president. And the number of cases has increased dramatically since Erdoğan assumed office in 2014.
