A Sudanese foreign ministry spokesperson has denied that a woman sentenced to death for apostasy would be released in a few days.

In a statement to CNN last night, Abu Bakr al-Sideeg al-Amin, said he is unaware of any plans to release Meriam Yahia Ibrahim Ishag "before a ruling from an appeals court".

Her lawyers have also expressed scepticism that she would be freed so quickly.

It comes after a senior Khartoum official told the BBC that Ms Ishag will be freed following worldwide protests about her treatment.

There has been widespread condemnation of the "barbaric" punishment of the 27-year-old, who gave birth to a daughter this week while shackled in her cell.

Ms Ishag was raised a Christian by her mother and has refused to renounce the faith.

However, a court ruled earlier this month that she is Muslim because that was her father's faith.

Her Christian marriage was annulled and she was sentenced to 100 lashes for adultery and death by hanging for renouncing Islam.

Sex outside a "lawful relationship" is regarded as adultery under Sudanese law.

Ms Ishag was condemned on 15 May under Islamic sharia law.
