KARACHI - The MQM, partner in the PPP-led ruling coalition in Sindh, is still unwilling to become part of the federal cabinet, The Nation learnt on Thursday. Well-informed sources disclosed that PPP had agreed to take four ministers from the MQM in the federal cabinet. But MQM Rabita Committee, in a recent meeting, decided that the party should not become part of the federal government but left the final decision in this regard to their party chief. Rabita Committee was of the view that working relationship with the ruling PPP in Sindh had not been improved despite a meeting of the MQM delegation with President Asif Ali Zardari. It said some controversies remained unresolved between the two partners. However, MQM will continue its support to the ruling PPP in the federal and provincial governments without becoming part of the federal cabinet, sources added. They claimed that the decision to this effect was final and only MQM chief Altaf Hussain could change it. However, despite repeated contacts, no MQM representative was available for comments on the latest situation.
