PML-Q on Wednesday issued show-cause notices to MPAs from the Unification Bloc, report said. PML-Q leader and Opposition Leader in the Punjab Assembly Chaudhry Zaheeruddin said it was illegal for the MPAs to first win the election on the PML-Qs ticket and then form a separate group. He said that initially 15 MPAs were issued notices and added that if the MPAs fail to respond satisfactorily then the party will send references for their disqualification to the Election Commission of Pakistan.
