Tony and Jane Nicklinson

Should the law ever give one human being the right to kill another?

That is the question at the heart of this special edition of Hardtalk which comes from the home of Tony and Jane Nicklinson.

Tony is completely paralysed; he wants to die. Jane wants to help him but currently British law stands in their way.

Stephen Sackur asks if Tony were to be killed would it be murder or mercy?
