The Muttahida Qaumi Movement (MQM) has decided to sue Pakistan Tehreek-e-Insaf chief Imran Khan for defamation.

MQM leader Wasay Jalil said that the party would sue Mr Khan for Rs50 billion for issuing statement against Altaf Hussain.

Imran Khan on Saturday held Mr Hussain responsible for the murder of his party leader Zahra Shahid, drawing strong reaction from the MQM.
