ISLAMABAD - The Senate Friday witnessed enraged proceedings that started with a token walkout by the combined opposition over unwary ministers that eventually exposed the political fault lines of the PML-N and main opposition party PPP.

The Upper House, which resumed with Chairman Syed Nayyar Hussain Bukhari, saw rising of temperature of the opposition members when the in-charge ministers failed to give satisfactory answers to their questions.

Taking advantage of the situation, Leader of Opposition Aitzaz Ahsen from PPP on a point of order highlighted the apathy of the ruling party saying neither Prime Minister Nawaz Sharif bothers to come to the Upper House nor his ministers come prepared.

He announced a token walkout on the sorry situation and left the House along with all the opposition members including the MQM. However, Information Minister Prevaiz Rasheed was successful in bringing the opposition back to the House. But it did not help to cool the tempers on both sides.

The situation flared up again after some time when Leader of Opposition Aitzaz Ahsen launched another attack through a point of order blaming the government for subjecting the family of former Chairman NADRA Tariq Malik to intimidation. This added fuel to the fire.

Powerful minister for Railways Khawaja Saad Rafique stood up and interrupted the Leader of Opposition. Khawaja Saad Rfique continued interrupting Aitzaz Ahsen thus forcing the Chair to intervene. He questioned the chair for allowing Aitzaz Ahsen to make his statement out of rules.

"I have used my discretion to allow him", the Chairman responded.

In the meanwhile Information Minister waiting in his wings stood up and challenged Aitzaz Ahsen's assertion of government threats and intimidation to the family members of the former Chairman NADRA. "This allegation is baseless and I categorically reject it," he said in the Senate in response to a claim by Leader of the Opposition Chaudhry Aitzaz Ahsan. "I contradict with all responsibility that the article published in newspapers about threatening the family members of former chairman Tariq Malik carried no weight and was beyond reality," the minister said. Chaudhry Aitzaz Ahsan had claimed that Tariq Malik and his family were threatened to get resignation from him.

The minister contested the claim and said, the stated claim carried no truth and its reply which bore all reality, had also published in the same newspaper."

He said that the Opposition Leader should also read the reply of that column to know the reality.

Aitzaz Ahsen after feeling humiliation quietly left the House amid smooth proceedings while the information also followed the suit.

The Chairman jumped to the remaining business on the agenda and allowed Senator Saeeda Iqbal to take up her calling attention notice seeking to draw attention of the minister incharge of the cabinet division regarding stopping of training programme under waseela-e-Rozgar, Benazir Income Support programme and non-payment of fee to trainers and stipend to beneficiary trainees.

Responding to it, Minister of State for Parliamentary Affairs Sheikh Aftab assured the House that programme will continue after due process of verification of the beneficiaries.

Later, Leader of the House Raja Zafarul Haq on a point of order condemned the powerful bomb blast at Peshawar and Nawab Shah Road accident and requested for offering Fateh for the departed souls and fast recovery of the injured.

Later, the House resumed discussion on the Peshawar blast in which all members who spoke on point of orders condemned the incident and sought concrete steps by the federal and provincial government in Khyber Pakhtunkhwa.

Among those who spoke about the incidents included Zahid Khan, Haji Adeel, Saeedul Hassan , Rehman Malik , Cl (retd) Syed Tahir Hussain Mashadi and Farhatullah Babar.

On a point of order, Senator Farhatullah Babar said that the decision to set up a military cantonment in Swat has sent a disturbing signal that despite successful military operation we are still in the 'hold' mould and had not reached the moulds of  'build' and 'transfer' to civilian control. This will embolden the militants as the move is an admission that the militants have not been conclusively and convincingly defeated, he said.

Secondly he said that the model of rewarding successful fight against insurgency would set up a dangerous precedence for other insurgency infected areas of the country.

Will the government keep building cantonments and allow permanent military presence in all areas of the Pakhtunkhwah. FATA and Balochistan where insurgency may have been subdued partially or totally he asked? This would lead to militarization of the civil society that must not be encouraged.

He said that from a purely military point of view setting up cantonment may make sense but it was a very unwise and thoughtless decision from the point of view of the state and asked the government to reconsider the decision to make cantonment in Swat.

Earlier during the Question Hour, Saad Rafique informed the house about the government efforts to make Railways a profit earning institution soon by running more cargo trains.

He said that the outstanding bills of various government departments on account of transportation charges to Pakistan Railways stand at 294 million rupees.

He said that Pakistan Railways has recovered an amount of 1.15 billion rupees from July 1‚ 2011 to November 30‚ 2013 from various departments.

He assured the House that the loss of Pakistan Railways would be significantly reduced in next four and a half years. Later, the House was adjourned till Monday.
