Sarabjit, 42, has been on death row since he was convicted for alleged involvement in four bomb attacks that killed 14 people in Punjab province in 1990. His family insists that he was wrongly convicted for the bombings.

The meeting is underway and a clear picture will emerge only after it ends.

Naek had earlier said a final decision on pardoning Singh would be made by President Asif Ali Zardari and Prime Minister Yousuf Raza Gilani.

The Minister will also consider the Indian government's clemency appeal for Sarabjit, sources said.

Sarabjit was originally set to be hanged on April one and his execution was deferred for 30 days by President Pervez Musharraf. This was done so that the new Pakistan People's Party-led government could review his case following India's appeal for clemency.

Pakistan's Supreme Court had earlier turned down Sarabjit's mercy petition.

After Prime Minister Yousuf Raza Gilani intervened in the matter, Pakistani authorities put off Sarabjit's execution "till further orders".
