A Saudi judge has sentenced a political activist to 300 lashes and four years in prison for calling for a constitutional monarchy in Saudi Arabia, his rights group said.
Omar al-Saeed is the fourth member of the Saudi Civil and Political Rights Association (ACPRA) to be jailed this year after the group issued statements attacking the ruling family over its human rights record and calling for democracy.
Saeed did not have legal representation at the secret hearing when he was sentenced on Sunday, ACPRA said in a statement on its website.
"It's just another troubling instance of Saudi authorities' absolute refusal to countenance any activism or criticism of Saudi policies or human rights abuses," said Adam Coogle, Middle East researcher at Human Rights Watch.
A spokesman for the Justice Ministry said he could not comment on the report or confirm its accuracy.
US-allied Saudi Arabia is ruled by the al-Saud family together with powerful clerics from the country's Wahhabi school of Sunni Islam.
King Abdullah is the prime minister and he appoints the government, which includes top princes in the roles of foreign, interior, defence and intelligence ministers. Most senior princes also have extensive business interests.
During the Arab Spring in early 2011, protests were restricted to the Shia minority in the Qatif district of Eastern Province.
Unrest among the Sunni majority was avoided after King Abdullah pledged $110 billion in spending on social benefits and top clerics and tribal leaders said people should back the ruling family.
Foreign analysts say there appears to be little public demand for big political changes in Saudi Arabia now, although they point to evidence on social media of growing frustration at corruption, poverty and poor state services.
