'"It is an excellent opportunity for India to raise this issue by embarrassing Pakistan at every fora. Sulking quietly does not help...... The first thing is to heap international calumny and embarrassment on Pakistan", party spokesman Abhishek Singhvi told reporters.
He said after the Mumbai attacks in 2008, it was felt at that time that the most isolated country in the world was Pakistan.
"I would like some of that policy to come back. We are not critical of the government we are exhorting the government to take steps which we took in November, 2008", he said.
Singhvi said that it reflected poorly on Pakistan that its judicial system is not that powerful even to keep a UN,US& internationally recognized terrorist, behind the bars.
"Threat perception against India rises with Rehman Lakhvi's release. PM Modi's flip-flops on foreign policy with Pakistan costing us dear", another party spokesman Sanjay Jha tweeted.
#LakhviRelease is an insult to the memory of the victims of 26/11. BJP government must convey this is unacceptable to India", another spokesman and former Union Minister R P N Singh said on Tweeter.
