ISLAMABAD, Feb 12: The Senate on Monday was prorogued amid a chaos when the combined opposition refused to listen to the minister of state’s winding up speech on completion of the two-day debate on law and order and opted to stage a walkout to protest what was termed as worst-ever electoral abuse in Karachi by-election and killing of an office-bearer of Pakhtoonkhwah Milli Awami Party (PMAP).

The upper house, which was convened on the requisition of the opposition to debate a three-point agenda, did not take up two remaining items of Civil Aviation Authority and the PIA, and surprisingly the opposition also ignored it.

The government has already decided to summon 37th Senate session again on Friday to cover the deficit in the calendar year days.

Deputy Chairman Mir Jan Muhammad Jamali who chaired the session described opposition’s walkout and sharp reaction to by-election happenings as a pre-planned move to score points.

As soon as the last speech of opposition was over, Minister of State for Interior Zafar Iqbal Warriach was invited by the chair to deliver his winding up speech.

The opposition, however, did not allow him to speak as opposition leader Mian Raza Rabbani stood up and started a fiery speech by accusing the ruling party in Karachi to have shown worst state terrorism during the by-election in which MQM’s Capt (retd) Akhlaq Hussain won against PPP’s Nafees Siddiqui.

"The voters were harassed, made hostage and polling staff impersonated during the daylong show of state oppression to steal the by polls results,” he said.

Pointing towards the minister of state, Mr Rabbani said: "How you could wind up the speech before answering to the house what had happened to the voters and candidate in the by-election!”The entire opposition lawmakers including those of the MMA and the PMAP stood up in unison to protest government’s attitude in the by-election.

MQM’s Babar tried to respond to the fierce opposition voices but he too fell short of sufficient support in the house.

Earlier, the house witnessed rowdy scenes when PMAP’s Raza Mohammed Raza interrupted a female treasury senator from Balochistan Parigul Agha during her speech.

Mr Raza used un-parliamentary language to condemn the senator for using words of appreciation for President General Pervez Musharraf, terming it shameful to support a dictator whose hands were immersed in blood of Pakhtoon and Baloch people.

Both the lawmakers exchanged serious abuses against each others which the chairman expunged from the house record while fellow senators tried to pacify them as well the chair.

Leader of opposition Mian Raza Rabbani and minister of state for parliamentary affairs Kamil Ali Agha played their role in cooling down the tempers from both the sides as the chairman termed it extremely unfortunate.

During the debate on law and order, the speakers asked the government to discontinue its cooperation with the US in its war on terror to save the country from its negative and destructive repercussion in shape of bombing on its territory and suicide bomb attacks.
