SANAA - Yemen's President Ali Abdullah Saleh said on Saturday he would leave power in the coming days, the closest the veteran leader has come to announcing he plans to step down after nine months of mass protests against his 33 year rule.

"I reject power and I will continue to reject it, and I will be leaving power in the coming days," Saleh said in a speech on state television.

Saleh has been clinging to his position while opposition and ruling party representatives cast about for a formula to see through a transition-of-power deal.

"I call on my supporters to persevere and to confront any challenge," Saleh said.

Protests against Saleh's rule have paralysed Yemen, weakening government control over swathes of the country and fanning fears al Qaeda's regional wing may use the upheaval to expand its foothold near shipping routes through the Red Sea.  

Saleh has thrice backed out of signing a Gulf-mediated power transition deal. The opposition says the government is holding up negotiations after Saleh's return from Saudi Arabia, where he had gone for treatment after a June assassination attempt.  

Abdulghani al-Iryani, a Yemeni political analyst, said: "This is just Saleh's latest line. I don't think it is really anything new. I remember he once said he would be ready to leave any day, so I don't think he means what he said."

Saleh has made many verbal concessions during the protests against him which began in January, including promising to step down in return for immunity from prosecution.
