Home Minister Sushilkumar Shinde today said he will have a look at the mercy petition of Parliament attack case convict Afzal Guru only after the Winter Session of Parliament.

He said the file related to the mercy petition of Guru, returned by President Pranab Mukherjee for review by him, was still with the Home Ministry.

"When Parliament is over, I will ask what is the status (of Guru's file). It is in the Ministry but has not come to me yet. I have to see his file in detail. I have to see it in depth," he said at the "Agenda-Aaj Tak" programme here organised by TV Today Group.

The ongoing Winter Session of Parliament will come to an end on December 20.

Asked about the secrecy that was maintained regarding hanging of 2008 Mumbai attack terrorist Ajmal Kasab, Shinde said such operations should always be kept a secret.

"If terrorists can maintain secrecy about their attacks, why cannot the government keep secrets," he said.

The Home Minister said his experience of having worked as a police sub-inspector and also as Maharashtra Chief Minister had helped him in secretly carrying out along the plan of execution of Kasab in Yerawada jail in Pune on November 21.
