BJP leader, Sushma Swaraj termed as a "cold blooded murder" the death of Sarabjit.
"It is a cold blooded murder. This is not the way civilised nations behave," she wrote on microblogging site Twitter.
Punjab Chief Minister, Parkash Singh Badal demanded an independent probe by an international agency into the circumstances leading to death of Sarabjit.
Badal also criticised the Centre's approach in handling the matter.
Describing the death of Sarabjit as a "murder", Badal said the Union Government must raise this issue at all international foras.
"The government must have taken strong steps at diplomatic level and it failed in doing so," he told reporters here at his residence.
BJP leader, Ravi Shankar Prasad described Sarabjit's death as a "cruel murder" and accused the Government of being indifferent to his condition in a Pakistani jail.
"He was in Pakistani jail and the responsibility was of the Pakistan government to ensure his safety and security. But, I am pained at the indifference of the Government of India," Prasad, BJP's Deputy Leader in the Rajya Sabha, said.
