We will be discussing Pakistan's controversial blasphemy law with journalist Shehrbano Taseer whose father - Punjab governor Salman Taseer - was killed for speaking out against it.

The killing ignited a debate in Pakistan with many critics calling for the law to be amended or scrapped, saying it was being used to victimise liberal politicians and religious minorities.

But extremist groups have celebrated Taseer's killer, calling him a hero who is defending Islam.

So has the blasphemy law become a political tool and should it have a place in today's Pakistan?

Also joining the discussion will be Asma Jahangir, a well-known human rights activist, and Amjad Waheed, an Islamic scholar.
