Pakistan's ousted prime minister Nawaz Sharif on Monday returned to the country from the UK to face corruption and money laundering charges in the Panama Papers scandal.
He was in London to be with his ailing wife Kulsoom who is undergoing treatment for throat cancer.
Sharif, 67, decided to return after consultations with senior party leaders including his younger brother and Punjab province Chief Minister Shahbaz Sharif in London, party officials said.
The aircraft carrying him landed here at around 7.30 AM and a confident Sharif came out, waved to his supporters and left in official protocol, TV news reports showed.
Pakistan Muslim League-Nawaz (PML-N) officials said that he would stay in Punjab House in Islamabad and hold meetings with party leaders on Monday and Tuesday.
"He (Sharif) would appear before the accountability court tomorrow (September 26) to defend himself in three corruption cases," the officials said.
Sharif stepped down after the Supreme Court disqualified him on July 28 from continuing in his office for dishonesty and ruled that corruption cases be filed against him and his children.
The National Accountability Bureau (NAB) has filed three cases of corruption and money laundering against Sharif, his sons—Hassan and Hussain, daughter—Maryam, son-in-law -- Safdar, and Finance Minister Ishaq Dar in the Accountability Court in Islamabad and Rawalpindi recently.
The anti-graft body last week froze the bank accounts and seized properties of Sharif and his family members to put pressure on them to appear before the court.
Earlier, Sharif skipped a court hearing last week to defy the cases. His family has alleged that the cases are politically motivated.
Maryam said that Sharif was returning to face cases for the sake of his people.
"Knowing what he faces is not accountability, the man decides to return. It is not about this person anymore. It is the battle of 200 million (Pakistanis)," she said in a tweet.
Sharif last month went to London to see Kulsoom who has undergone three successful surgeries for her cancer.
Kulsoom contested on Lahore's NA-120 seat that fell vacant in the wake of his disqualification and won.
Their children are still in London as he prepares to appear before the court in Islamabad on Tuesday.
The court has also summoned Maryam, Hussain, Hasan and Safdar but it was not immediately known if they would appear before the court on Tuesday.
Meanwhile finance minister Dar, who also returned from London, appeared today in an anti-corruption court.
The court had issued a bailable arrest warrant against him for failing to appear before it.
Dar's lawyer had deposited surety bonds worth Rs one million to avoid his arrest.
The court, after brief hearing, postponed the case of Dar till September 27 and asked him to appear again as he would be formally indicted by the prosecution in a corruption case for having assets beyond his known sources of income.
