The general - who now finds himself centre stage in an international crisis - was born in Delhi in August 1943. His family emigrated to Pakistan during the partition of the Indian sub-continent.
His rise through the ranks came despite the fact that he does not belong to the predominantly Punjabi officer class of the Pakistani army - but to an Urdu-speaking family in Karachi.
He began his military career in 1964. Early on, he reportedly commanded artillery and infantry brigades before going on to lead various commando units.

He reportedly underwent two spells of military training in the UK and was appointed director-general of military operations by the now-exiled former prime minister, Benazir Bhutto, before taking full charge of the armed forces.

Top job

General Musharraf rose to the top job in 1998 when Pakistan's powerful army chief, General Jehangir Karamat, resigned two days after calling for the army to be given a key role in the country's decision-making process.

Prime Minister Sharif: Increasing tension with general

It was the first time an army chief of staff has ever stepped down and many observers took it as a sign that Prime Minister Nawaz Sharif's political power had become strong enough to secure the long-term future of civilian administrations.
Some independent commentators suggested that General Musharraf's promotion came precisely because he did not belong to the Punjabi officer class.
They say the Prime Minister believed that Musharraf's ethnic background would leave the
general unable to build a powerbase.

Kashmir crisis

During the Kashmir crisis in 1998, General Musharraf was regularly seen briefing the media and making appearances on state television.But while he said that Pakistan-backed militants were preventing Indian gains, he and other senior generals were reportedly increasingly angry at the prime minister's attempts to find a diplomatic way out of the crisis.

Mr Sharif's moves led to speculation that the military did not have the full political backing of the government and he eventually ordered a full withdrawal. General Musharraf was the first senior figure to acknowledge that Pakistani troops had entered the Indian-administered sector during the fighting. Previously, Pakistan had said that the forces had all been Islamic militants determined to take territory from the other side of the Line of Control.

In contrast, India's ruling BJP party sought to make electoral capital out of what it saw as a great military victory. While being credited as one of the principal strategists behind the Kashmir crisis, General Musharraf also made clear he did not oppose efforts to ease tension with India. Ties worsened after a hijack in December 1999 But any hopes that his takeover in a coup might herald a stabilisation in ties with India - or even a new start - appeared displaced in the first 20 months of his rule. Tension on the sub-continent initially increased markedly - with both sides adopting hostile positions.

The hijack of an Indian Airlines plane to Afghanistan in 1999 - which India blamed on Pakistani-backed groups - and a rising tide of violence in Kashmir plunged relations to a new low.
In July 2001, General Musharraf held his first summit meeting with Indian Prime Minister Atal Behari Vajpayee at Agra - but failed to make much headway in the Kashmir dispute.
Before going to India, he had named himself president in a bid to consolidate his grip on power.
General Musharraf has also firmly resisted outside pressure to move quickly to restore civilian rule.

After the coup he suspended the national assembly. He has said there can be no question of elections until October 2002 - the deadline set by Pakistan's Supreme Court

Mr Jamali, 58, is described as a moderate, middle-of-the-road leader.
He was among several senior members of former prime minister Nawaz Sharif's Pakistan Muslim League party who defected after the military coup which deposed him in 1999.

They formed their own faction, the PML-Q, which won the most seats in general elections in October.

Since the coup, the PML-Q has remained close to the military regime and Mr Jamali has already indicated that he is willing to co-operate with President Pervez Musharraf, even if he continues to remain the chief of the army.

Veteran

Mr Jamali began his political life as a member of the Pakistan People's Party (PPP), which he joined in the 1970s, and has since been regularly elected to the national and provincial parliaments.

He has featured in various national cabinets - first under the left-leaning Zulfiqar Ali Bhutto in the 70s, then under military dictator Zia ul Haq in the 80s. He also served in the civilian government led by Mohammad Khan Junejo later in that decade.
In 1988, he became acting chief minister of Balochistan, a post to which he was reappointed following the dismissal of the Benazir Bhutto government in 1996.

In elections the following year, he became a senator in Islamabad.

Polyglot

Married with three sons and a daughter, Mr Jamali comes from a landowning family which has played an active role in Pakistani politics for over 50 years.

He was born in the village of Rowjhan, and attended the prestigious Royal College at Murree and Aitchison College in Lahore before gaining a Masters degree at Punjab University.

He speaks English well and is also fluent in the main local languages including Urdu, Punjabi, Sindhi, Pashto and Balochi. His critics believe it is unlikely he will challenge General Musharraf. But observers point out that Mr Jamali has asserted himself on occasion in the past.

They add, however, that he is likely to come under considerable pressure in his new job.
