"The meeting will be held in the Ministry of Foreign Affairs", the spokesman said. Islamabad also allowed them to be accompanied by an Indian embassy official as requested by New Delhi, The Hindu reported.
Pakistan, earlier this month, had rejected India's plea for consular access to Jadhav, claiming that New Delhi wants to extract information gathered by its "spy".
Foreign Office Spokesperson Dr Mohammed Faisal took to Twitter to break the news.
The spokesperson said that visas have been issued to the wife and mother of agent Kulbhushan Jadhav and their meeting would take place in Islamabad on December 25. "We await Indian decision in this regard".
In response to questions about the visit of the mother and wife of Indian prisoner Kulbhushan Jadhav to Pakistan to meet him on 25 December, the spokesperson said the modalities were still being worked out. "However, the subsequent Indian behaviour, trying to use the listing of these groups to malign Pakistan forced Pakistan to suggest a comprehensive list - of all terrorist groups irrespective of their ideology, religion and geography etc". Pakistani officials said there were still two forums of appeal left for Mr. Jadhav even if the Army Chief turns down his mercy appeal. Jadhav, a former Indian Navy officer, was arrested in Pakistan and was charged with espionage. Pakistan earlier this week filed a counter-memorial in the ICJ.
The ICJ halted his execution on India's appeal pending the final verdict by it.
While Pakistan claims that Jadhav was arrested by security forces from Balochistan province on March 3 past year after he reportedly entered from Iran, India maintains he was kidnapped from Iran where he had business interests.
