ISLAMABAD - The joint opposition yesterday boycotted the first day of the Senate session with the announcement to continue the boycott daily until Prime Minister Nawaz Sharif would come in the house and explain his position over Panama leaks.

The announcement from Leader of the Opposition in the Senate Aitzaz Ahsan came before the opposition boycotted the first day of the Senate session followed by a walkout on the same issue with the demand from PM to 'come and explain his family's position on Panama leaks.

The opposition first staged a walkout for 28 minutes on private members' day against the absence of prime minister from the house. Again, it boycotted the house saying it had formed a strategy to continue with the boycott until their demand is met.

Aitzaz said names of Prime Minister's family members had been revealed in Panama Papers and being Leader of the House, he should come in the house and reply to these allegations. He further said that premier should declare his assets and the details of taxes he paid so far before the house. "But he is escaping from the Senate and instated is hurling charges at the opposition."

Giving the example of the recent arrest of finance secretary Balochistan by NAB on charges of Rs 700 millions, the opposition leader questioned why action could not be taken against prime minister's son for what he said he owned offshore wealth amounting to Rs 70 billion.

In response, Leader of the House Raja Muhammad Zafarul Haq said Aitzaz had one-point agenda and that was to target the prime minister. At least two treasury senators wanted to speak on the issue but the chair did not allow them saying, “let me first dispose of the agenda.”

At the end of the sitting, the parliamentary leader of the PML-N in the house, Mushahid Ullah Khan accused that opposition was unnecessarily criticising the PM and trying to exploit the situation arising out of the Panama leaks. "It is purely discretion of the premier to come in the house," he said adding that PM had been coming to the house earlier. He reiterated the government's stance that PM's name was not directly in the papers and said that matter would be decided at the legal forum and not inside the parliament.

He accused the PPP leadership of doing corruption in the past and alleged who had received money from former president Punjab Bank Hamesh Khan. He also referred to the emergence of names of PTI leader Aleem Khan in the leaks, Zulfi Bokhari as well as Abdul Rehman Malik and offshore property of Jehangir Tareen.

In the meantime, senators, belonging to Fata also staged walkout from the house against non-fulfilment of demands of the Fata and Khyber Pakhtunkhwa teachers, despite a commitment made by the federal government.

Speaking on a motion about the ways to stop smuggling in the country, the lawmakers from both sides of isle called for an effective mechanism to check smuggling and added that anti-smuggling agencies were involved in this illegal activity. The mover of the motion PML-N Senator Chaudhry Tanvir Khan said the nation was still facing consequences of missing Nato containers.

The lawmakers claimed that not only goods but also material used in preparation of suicide jackets, drugs, arms and explosives were smuggled into Pakistan. A legislator alleged that the Afghan intelligence agency-N DS-was smuggling arms into Pakistan to be used for Afghan and Indian operatives for destabilisation of the country.

The National Accountability (Amendment) Bill 2015, aimed at curtailing powers of the anti-corruption watchdog, was dropped due to absence of mover. However, the chair asked the mover to forward notice to him to consider this bill on next private members' day.
