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.'
