ISLAMABAD: In a statement early Monday, Pakistan Peoples Party leader Khurshid Shah claimed his party was responsible for seventy percent of what Pakistan Tehreek-e-Insaf (PTI) Imran Khan deems 'success.'

"If anyone is to be given credit, it should be Jamaat-e-Islami Chief Siraj ul Haq, who first knocked the court's door," Shah said.

The opposition leader alleged it was decided with PTI's Shah Mehmood Qureshi to jointly announce the opposition's prime ministerial candidate but Khan was quick to nominate Sheikh Rashid.

"Khan's statements could endanger the opposition's unity," Shah said.

Responding to Khan's criticism on PPP's Co-Chairman Asif Ali Zardari, Shah said the PTI chairman needs to change the way he thinks if he believes he can take on Pakistan Muslim League - Nawaz (PML-N) all by himself.
