The Syrian government said on Saturday it would not hold talks with any party wishing to discuss the question of the presidency, calling President Bashar Assad a "red line" as it confirmed its participation in UN-led peace talks next week."We will not talk to anyone who talks about the position of the presidency. Bashar is a red line, the property of the Syrian people," Foreign Minister Walid al-Moualem said during a televised news conference in Damascus. "I advise them that if this is their thinking, they shouldn't come to the talks.""They must abandon these delusions."
