A Church group supporting the family in November said they were being pursued by vigilantes as they awaited her release from protective custody.
Hardline Islamists had been knocking on doors in the neighbourhood where her husband and daughters live, raising fears that they could be killed before she has a chance to leave Pakistan.
“After all this beleaguered family has been through they deserve to be together. Now is the time to free Asia so she and [her husband] can join them,” said Wilson Chowdhry of British Pakistani Christians. “Basically the government has needed to keep her under lock and key just to keep Asia Bibi safe, meaning that through this whole process she has been continuing a life of severe restriction, albeit a more comfortable one.”
The government of Prime Minister Imran Khan belatedly arrested the ringleaders of religious protests that had almost brought the country to a standstill after Mrs Bibi was acquitted.
Khadim Hussain Rizvi, chief of the Tehreek-e-Labbaik Pakistan (TLP) party which led the demonstrations remains on remand with several of his lieutenants.
