It is not clear what prompted Islamabad to allow Jadhav's wife to meet him in Pakistan, the Express Tribune reported.
Pakistan's foreign office in the national capital said it would allow Kulbhushan Jadhav to meet his wife. "A Note Verbale has been sent to the Indian High Commission in Islamabad, today", a foreign office statement said.
Kulbhushan Jhadev, a serving Commander of the Indian Navy, working with Indian Intelligence Agency RAW was apprehended by Pakistan law enforcement agencies previous year after he illegally crossed over into Pakistan. He was sentenced to death by a military court. A military court sentenced him to death for the alleged espionage.
New Delhi has repeatedly sought access to the convicted spy but Islamabad denied the permission on the ground that consular access in cases related to spies were not applicable.
The Indian government had moved a visa application for his mother to go and meet Jadhav in Pakistan.
India had approached the International Court of Justice (ICJ) in May seeking a provisional stay to the execution of Jadhav which was granted.
Pakistan claims its security forces arrested him from restive Balochistan province March 3 a year ago after he reportedly entered from Iran. The suspect was said to be an officer of the Indian navy working for the covert agency to destabilize Pakistan. As India took the case to International Court of Justice (ICJ) in May, Pakistan even told the United Nations court that "Pakistan doesn't see the merit in a state which sends a spy and is seeking access to a tool for terror".
Last month, the Pakistan Army had said it is close to a decision on the mercy petition of Jadhav. By an order of June 13, 2017, the President of the ICJ had fixed September 13, 2017 and December 13, 2017 as the respective time limits for the filing of a memorial by India and a counter-memorial by Pakistan.
