Pakistani opposition leader Benazir Bhutto has been released from house arrest in the capital, Islamabad.
The order was imposed early on Friday, blocking Ms Bhutto's attempt to lead a rally against the emergency rule declared by President Pervez Musharraf.
The United States had criticised the move saying that she must be "permitted freedom of movement."
Ms Bhutto has vowed to wage a campaign aimed at forcing General Musharraf to stand down as head of the army.
A three-day detention order was served on the former prime minister after she tried to cross the heavy police cordon set up outside her home on Friday.
Police had surrounded the house early in the morning with roadblocks and coils of barbed wire to prevent her from addressing a rally in the neighbouring city of Rawalpindi.
Under emergency rule announced last week, such public gatherings have been banned.
Officials said it was a temporary measure because of a fear of suicide bombers attacking the planned rally, and that it would be lifted by Saturday.
Ms Bhutto made several attempts to leave her home but was turned back. She finally emerged to address the media through a megaphone from behind the barricades.
She repeated opposition demands that Gen Musharraf should lift the state of emergency, resign as army chief and hold elections by mid-January.
"We are calling for the revival of our constitution and respect for our judiciary," she said.
"We are calling for General Musharraf to keep his commitment and retire as chief of army staff on 15 November."
The BBC 's Chris Morris in Islamabad says it has been a good day for Ms Bhutto bolstering her democratic credentials at a time when other opposition parties still believe she plans to do a deal with Gen Musharraf.
Our correspondent says she is putting him under pressure at home while his Western allies are putting him under pressure abroad.
