Right-to-die campaigner Paul Lamb has told ITV News the failure of British law to grant assisted suicide makes us an "extremely cruel country".
Paul Lamb has adopted the legal fight of locked-in sufferer Tony Nicklinson, who was left paralysed after suffering a stroke in 2005.
Mr Nicklinson broke down in tears on August 16 last year as he told ITV News he was left "devastated and heartbroken" at the High Court's decision to deny him a right to die.
Within days, Mr Nicklinson's health rapidly deteriorated after he contracted pneumonia and began refusing food. He died on 22 August 2012.
A heavily-paralysed man has waived his right to anonymity to become the new figurehead of a right-to-die campaign.
Paul Lamb, who was previously referred to as "Patient L", has adopted the legal fight previously fronted by locked-in sufferer Tony Nicklinson.
Mr Nicklinson died last year, days after losing his High Court battle to be permitted to die with the help of a doctor.
Mr Lamb's assumption of his legal challenge, which was granted by the Court of Appeal last month, will be joined by a case brought by Mr Nicklinson's widow Jane Nicklinson.
She is pursuing a claim in her own right that she suffered pain, distress and injury as a result of her husband's inability to lawfully end his own life.
Both cases will now be heard in the Court of Appeal next month.
Paul Lamb is "clear and determined" to see a change in the law over the right-to-die, his solicitor has said.
Saimo Chahal, of Bindmans LLP, has said:
My client, Paul Lamb has decided that he is willing to speak about his situation publicly now having discussed with family and friends his wish to terminate his life with the help of a doctor at the right moment. He is willing to engage in the debate as Tony Nicklinson did. He is clear and determined in his wish to see a change in the law which he considers wholly wrong and out of date for a person in his situation, and for others like him.
