Doctors can turn off life support being given to a new mum who has coronavirus and is in a coma, a judge has ruled.
Mr Justice Hayden made the decision against the wishes of the woman's family, including her husband and sister, who believe she should be given more time.
However, medical experts say the woman, aged in her 30s, has "zero" chance of recovery.
The heartbreaking case was heard by the Court of Protection, where issues relating to people who lack the mental capacity to make decisions for themselves are analysed, late on Tuesday.
The judge said the woman, a Muslim who was married and also had a three-year-old daughter, could not be named.
Bosses at the University Hospitals of Leicester NHS Trust had asked him to rule that ending life-support treatment would be in the woman's best interests.
The woman's husband and sister want treatment to continue and that Muslims believe that only God can end life.
But the judge said evidence showed that doctors were no longer preserving the woman's life, but prolonging her death.
He concluded that ending treatment would be in her best interests and said she should be allowed to die with dignity.
Mr Justice Hayden said the woman's "life and hopes" had been extinguished by "this insidious virus", and a young family "split apart prematurely".
"This family is seeking a miracle," he said.
"This is a very young mother in circumstances of almost-unspeakable sadness."
He added: "It is a tragedy of an almost-unimaginable dimension."
Mr Justice Hayden said doctors had prepared a palliative care plan and the woman's family would be able to see her.
"The objective is not to shorten her life," he added. "(But) to avoid the prolongation of her death."
The judge was told that the woman suffered from Addison's disease - a rare disorder of glands that produce essential hormones.
He heard that she had developed Covid-19 while at home and been rushed to hospital a month ago when 32 weeks' pregnant.
Doctors had delivered her son by caesarean section shortly after she was admitted.
They said her pancreas had ceased to function and one lung had "died".
"Her chances of making any meaningful recovery are with the Covid are slim," a specialist overseeing her care told Mr Justice Hayden.
"The feeling of the whole team is that she has reached the point where it is, in essence, zero."
He said CT scans showed "essentially no normal lung function".
The woman's sister told the judge that the family was Muslim and believed that only God could end life.
"We believe in miracles," she said.
"When God has written our death, that is when we will die."
She added: "To unplug the machine, this is for us like asking someone to kill us."
The judge heard that the woman knew she was carrying a boy and had chosen a name for him.
