The Sindh government decided to file a case against Altaf Hussain in the UK for the violence happening in Karachi.
The Pakistan Muslim League-Nawaz government reiterated any kind of violence or statement against Pakistan, its existence and armed forces would not be endured.
Islamabad will exchange evidence of Muttahida Qaumi Movement (MQM) chief stirring violence in Pakistan with the UK police in the next few days, an official confirmed on Friday.
Officials said they have received strong evidence and documents against the MQM chief that fulfil the legal requirements of the UK government for taking action against Altaf Hussain.
According to the sources, the PML-N government might not seek MQM chief’s extradition because he is a British citizen and does not hold a Pakistani passport.
Federal Interior Minister Chaudhry Nisar Ali had announced to file a reference formally against Hussain to the British authorities only a day after the MQM chief sent an angry mob to attack media houses in Karachi.
Nisar had said that the centre would not allow a single person to hostage Karachi and its people.
Scotland Yard said it was investigating whether the Muttahida Qaumi Movement leader incited violence in Karachi when he addressed party workers and supporters from his north-London base last Monday.
