Lahore: Chanting supporters welcomed opposition leader Benazir Bhutto to Lahore on Sunday, ahead of a mass protest she is planning against President Pervez Musharraf's emergency rule this week.

Waving the black, red and green flags of her Pakistan Peoples Party, hundreds of frenzied activists shouted "Benazir Prime Minister!" and "Long live Bhutto", thrusting their arms in the air and making V for victory signs.

Bhutto intends to lead a procession of vehicles to Islamabad tomorrow to demand Musharraf quits as army chief, ends the emergency rule he imposed a week ago, restores the constitution and frees thousands of detained lawyers and opponents.

Police have vowed to block the convoy, just as they stifled a planned protest rally in the city of Rawalpindi on Friday - when Bhutto was held under house arrest for most of the day.

"I am here for democracy," Bhutto said on arrival at Lahore airport, where several hundred party activists and supporters managed to negotiate their way past barricades manned by police in riot vests wielding batons and shields.

Punjab province's elite police unit, with "No Fear" printed on their tracksuits, stood guard.

"Even if the Punjab government tries to create hurdles, we will go for our long march on November 13", she added, before getting into her white, bullet-proof Land Cruiser as supporters ran behind her waving banners and party flags.

Bhutto, who the United States hoped would end up sharing power with Musharraf after elections, described nuclear-armed Pakistan as a "pressure cooker" about to explode on Saturday.

In the face of pressure from US President George W. Bush, Musharraf yesterday said elections would be held by January 9, in line with a schedule that Bhutto had been insisting on.

However, Musharraf - who is waiting for a Supreme Court ruling to endorse his October election win while still serving as army chief - has not yet given a date for lifting emergency rule, or removing his army uniform.

Many Pakistanis expect Musharraf to go back on his promise to give up his uniform, as he did in 2004.

Bhutto supporters are praying her return to Pakistan after eight years of self-imposed exile to avoid corruption charges will mark a new beginning in troubled Pakistan.

"She is a symbol of democracy," said Mohammad Riaz Badar, a 74-year-old former song writer who was wearing a party flag tied around his neck.

"The dictatorship should end and she should be allowed to come to power. She has proved she is a brave woman. She is a daughter of a martyr," he added, referring to Bhutto's father.
