Pakistan's President-elect Asif Ali Zardari on Monday moved into the presidential palace, where he will be administered the oath of office as the new head of the State on Tuesday and will be unveiling his 'vision' to tackle the challenges facing the nation.

Zardari, 53, swept last week's presidential poll by bagging almost 70 per cent of the Electoral College votes. He will be sworn in by Supreme Court Chief Justice Abdul Hamid Dogar during a ceremony to be held in the Aiwan-e-Sadr (presidency) at 1 pm on Tuesday.

State-run PTV beamed footage on Monday afternoon of Zardari arriving at the presidential palace in the heart of the federal capital with his daughters Bakhtawar and Asifa and close aides. After some brief religious ceremonies, Zardari entered the mammoth building.

Shortly after former President Pervez Musharraf [Images] resigned last month, Zardari shifted from his private residence to the Prime Minister's House due to security concerns.

Reports suggested that Zardari's teenaged son Bilawal, who was made chairman of the ruling Pakistan People's Party after his mother Benazir Bhutto's [Images] assassination last year, is expected to arrive in Islamabad [Images] from Britain to attend the swearing-in ceremony.

Arrangements for the swearing-in ceremony began on Monday morning after the Election Commission formally notified Zardari's victory in Saturday's presidential poll.

After taking oath on Tuesday, Zardari will be presented a guard of honour by a tri-services contingent. He will later meet people from all sections of society.

Zardari will also address a news conference, during which he is expected to present his 'vision to take Pakistan forward, a strategy to counter terrorism and (steps) to strengthen the economy', state-run APP news agency reported.

Prime Minister Yousuf Raza Gilani [Images], the Chairman of the Joint Chiefs of Staff Committee and the three service chiefs will pay courtesy calls on Zardari after he is sworn in.

Zardari's estranged ally and PML-N chief Nawaz Sharif will be unable to attend the oath-taking ceremony as he will be leaving for London [Images] to be with his wife, who is recovering after a surgery.

The PPP organised several religious ceremonies ahead of Zardari's move to the Aiwan-e-Sadr. On Sunday, Zardari's family and PPP workers participated in a 'Quran khwani' ceremony at the presidential palace to seek blessings to help him overcome the challenges confronting Pakistan.

When Zardari arrived at the Aiwan-e-Sadr on Monday afternoon, a copy of the Quran was held over his head as he walked into the building flanked by his daughters. Several black goats were also sacrificed on the occasion.
