LAHORE: The controversial tribunal set up to investigate rigging in Pakistan Tehreek-i-Insaf`s intraparty polls has ordered expulsion of senior leaders Jehangir Tareen and Nadir Khan Leghari from the party.

Headed by Sindh High Court retired chief justice Wajihuddin Ahmed the tribunal alleged on Monday that both Tareen and Leghari had manipulated the intra-party polls held months before the 2013 general election, say media reports.

It also banned their reentry into party folds.

The tribunal also cancelled basic membership of Pervaiz Khattak, the Khyber Pakhtunkhwa chief minister, and ex-Lahore party chief Aleem Khan and barred them from attaining any party office.

Issuing show-cause notices to Arif Alvi, Saifullah Niazi and Qasim Suri, it summoned them for June 29 for probing their role in the rigging and irregularities in the intra-party polls.

A PTI spokesman said as party chairman Imran Khan had dissolved the tribunal all its decision were illegal and unconstitutional.
