Pakistan's Supreme Court is due to decide on January 29 whether to uphold its acquittal of a Christian woman at the center of a years-long blasphemy row.



Asia Bibi’s lawyer, Saiful Mulook, said he expected the judges to reject a petition by Islamists for a review of their decision last year to acquit her.



For Bibi, who has been in protective custody at a secret location since her acquittal in October, the court's decision could represent the final legal hurdle to her freedom.



Bibi spent eight years on death row for blasphemy, a hugely sensitive charge in Muslim-majority Pakistan.



The Supreme Court's decision to overturn her conviction ignited days of violent demonstrations, with radical Islamists calling for her killing as well as mutiny within the powerful military and the assassination of the country's top judges.



The government has since launched a crackdown on the Tehrik-e Labaik Pakistan (TLP) party -- the Islamist group driving the violent protests -- charging its leaders with sedition and terrorism.



But authorities also agreed to allow a final review of the Supreme Court's judgement.



The TLP party said on January 28 that it would not accept any decision in favor of Bibi's release and asked its followers to prepare for more protests.



Police have stepped up security around the Supreme Court in Islamabad ahead of the judges' decision.



Bibi has always claimed her innocence and said she will leave the country as soon as her legal battles are over. Her daughters have fled to Canada, where they have been given asylum.



Her lawyer also fled Pakistan after receiving death threats but returned to the country ahead of the Supreme Court's decision.



Approximately 40 people are believed to be on death row or serving a life sentence for blasphemy in Pakistan, according to a 2018 report by the United States Commission on International Religious Freedom.
