As Asia Bibi sits free at last in a secret location in Canada, the Pakistani Christian woman who spent years on death row after a false blasphemy charge thinks of those left behind still facing the same ordeal.

Nearly four months after the 54-year-old finally left Pakistan following a miscarriage of justice that caused worldwide outcry, she has the opportunity to rebuild a new life for her and her daughters.

Yet while she is enthusiastically grateful for the international efforts to free her, she says the world should know that Pakistan's harsh blasphemy laws have left many others still behind bars.

In her first ever newspaper interview, she told The Sunday Telegraph she had at times fallen into despair after being sentenced to death in a case condemned around the world.

She also spoke of her heartbreak at being forced to leave her homeland, amid fears she would be murdered by religious extremists even after Pakistan's supreme court had quashed her flimsy conviction.
