MQM spokesman Faisal Sabzwari made an announcement after a decision was made by the party’s coordination committee in Karachi and London.

MQM leader Altaf Hussain had sought the opinion of the people whether the MQM would quit the PPP-led coalition. It appears that the PPP's days are numbered.

President Asif Ali Zardari is weighing various options to  tide over the crisis after the Jamiat Ulema-e-Islam with seven members in the National Assembly quit the government recently. MQM has 25 members in the National Assembly.

PPP has only the support of the Awami National Party in the lower house.

Options available for Zardari are either dissolution of the National Assembly or an alliance with PML (Q).

The MQM has not left the coalition in Sindh government to press its demands for an end to corruption.
