According to sources, Home Minister P Chidambaram forwarded the file to President Pratibha Patil after consulting Law Minister Veerappa Moily and seeking clearance from Prime Minister Manmohan Singh.
"Mercy petition filed by Tabassum, wife of the Parliament House attack convict Afzal Guru, should be rejected. Nature of the crime committed is heinous and he deserves no mercy," a ministry note said.
Guru was awarded the death sentence by a Delhi court on December 18, 2002 after being convicted of conspiracy to attack Parliament on December 13, 2001, waging war against the country and murder.
The death sentence was upheld by the Delhi high court on October 29, 2003 and the Supreme Court rejected his appeal two years later on August 4, 2005. A sessions court also fixed the date of his hanging on October 20, 2006 in Tihar jail.
Following this, Afzal filed a mercy petition with the President, who forwarded it to the home ministry for its comments. The home ministry had sent the file to the Delhi government's home ministry for its comments, as per the laid out procedure.
On May 18, 2010, the delhi government has backed the death sentence but added that there is a need to examine the implications of the law and order situation while carrying out the Supreme Court's verdict
Reacting to the development, main Opposition Bhartiya Janata Party said the decision was inevitable.
Speaking to rediff.com on Wednesday, party's senior vice president Mukhtar Abbas Naqvi said: "The government of India was forced to take the decision under pressure from the BJP and the people of the country, who felt strongly that Afzal Guru should not be pardoned," he said.Hang me, I am fed up with confinement, says Afzal
Sentence delayed is sentence denied
When cowards run the State, the nation bleeds
Don't compare '93 blasts with Parliament attack
