Egypt's President Hosni Mubarak has said he will stay in office and transfer all power only after September's presidential election.
His comments in a national TV address confounded earlier reports that he was preparing to stand down immediately.
Mr Mubarak said he would delegate some powers to Vice-President Omar Suleiman, but would ignore "diktats from abroad".
Thousands of anti-government protesters in Cairo's Tahrir Square reacted angrily to his announcement.
"I express a commitment to carry on and protect the constitution and the people and transfer power to whomever is elected next September in free and transparent elections," Mr Mubarak said.
Directly addressing protesters "in Tahrir Square and beyond" in what he said was "a speech from the heart", Mr Mubarak, 82, said: "I am not embarrassed to listen to the youth of my country and to respond to them."
He apologised to the families of protesters killed in clashes with the security forces in recent weeks, and said those responsible for their deaths would be punished.
He added that the country's emergency law would only be lifted when conditions were right.
Egypt's military had earlier said it was standing ready to "protect the nation".
Negotiations between the government and opposition groups have made little progress, with protesters disillusioned at plans for reform put forward by Mr Mubarak's government.
The US government had in recent days stepped up its call for the protesters' concerns to be addressed.

Susheela Raman hails from the movement of immigrant and second-generation musicians from the Indian subcontinent based in Britain, who perform a fusion of traditional and classical forms from their homeland with contemporary beats and dancehall tracks from Western Europe. Raman was born to immigrant parents in London in 1973, and her family soon moved closer to the subcontinent, taking a home in Australia, where she soon started learning and performing South Indian classical song. With a bevy of recitals under her belt, she began working with more blues-based music (soul, rock, R&B) for a while, alternating between that and new studies in Hindustani song with Shruti Sadolikar. Returning to England within a few years, she began work on the idea of fusing Indian classical forms with more contemporary Western ones. Aided by Sam Mills, who had done similar projects with one of the contemporary Baul singers, Raman worked with a huge number of foreign artists on the Salt Rain project, released in 2001. She was nominated as the first world music artist for the British Mercury Prize, and satisfied with the results of Salt Rain, Raman used the same basic guidelines to create Love Trap, released in mid-2003.
