ISLAMABAD: Citing 'reservations over some matters', the Muttahida Qaumi Movement did not attend a joint meeting called by opposition party leaders on Tuesday to formulate a joint strategy after the prime minister’s speech in parliament addressing allegations stemming from the Panama Papers leak.

Sources told Geo News that the leadership of the MQM had problems with how some leaders in the opposition had also been named in the Panama Papers for having offshore companies.

The joint opposition held the meeting today to devise its future strategy after the prime minister’s speech in the assembly the previous day. The meeting was chaired by Leader of Opposition in the National Assembly Syed Khursheed Shah.

Pakistan Muslim League – Quaid chief Pervez Elahi said that the opposition was united. "We will present 70 questions to the government and add to their worries."

On Monday, Prime Minister Nawaz Sharif asked Parliament to form a committee to investigate allegations stemming from the Panama Papers leak but opposition lawmakers walked out, saying he had evaded questions about his family's affairs.

"We are not afraid of anything and present ourselves for accountability," Nawaz told Parliament. “I request the House to join me in formulating a charter, like the one I had signed with former Prime Minister Benazir Bhutto (late), to investigate Panama Papers,” he added.

The prime minister, who presented his tax record before the House and gave details about his family’s assets abroad and sources of financing, said further evidence could be presented to the committee.

Earlier, PML-N parliamentarians raised full throated slogans on the arrival of Prime Minister Nawaz Sharif in the House. The PTI members retaliated with anti-Nawaz slogans when their party Chairman Imran Khan entered the National Assembly hall.
