The Supreme Court has given 30 days to authorities concerned to bring back Pakistan's former Ambassador to US Hussain Haqqani.

The directions were given during hearing of the Memogate case by a three-member bench of the apex court, headed by Chief Justice of Pakistan Justice Saqib Nisar, in Islamabad on Wednesday.

Foreign and Interior Secretaries also appeared before the bench.

Earlier this year the Supreme Court (SC) resumed the hearing of the Memogate case. The chief justice had issued summons for Haqqani.

This development came as a three-judge bench headed by CJP Mian Saqib Nisar heard the petitions for granting right of vote to overseas Pakistanis in the upcoming general elections 2018.

The Memogate controversy revolves around a memorandum allegedly drafted by Ambassador Haqqani at the behest of then president Asif Ali Zardari and addressed to US Admiral Mike Mullen.

It ostensibly sought help of the Obama administration in the wake of the Osama bin Laden raid to avert a military takeover of the civilian government in Pakistan, as well as assisting in a civilian takeover of the government and military apparatus.
