King Abdullah of Jordan has said Syrian President Bashar al-Assad should step down in the interest of his country.
"I believe, if I were in his shoes, I would step down," he has told BBC World News in an exclusive interview.
"I would step down and make sure whoever comes behind me has the ability to change the status quo that we're seeing."
Neighbouring Jordan has been highly critical of Syria's crackdown on anti-government protesters in recent months.
King Abdullah said the president should begin a new era of political dialogue before leaving office.
"If Bashar has the interest of his country, he would step down, but he would also create an ability to reach out and start a new phase of Syrian political life."
Jordan is not the first Arab country to be critical of the Syrian crackdown.
