A High Court judge is preparing to analyse evidence in a life-support dispute centred on a seriously-ill five-year-old girl.
Mr Justice MacDonald has heard that Tafida Raqeeb "very serious" brain damage.
Doctors treating Tafida, who turned five on June 10, at the Royal London Hospital in Whitechapel say the damage is permanent and and there is no chance of recovery.
Bosses at Barts Health NHS Trust, which runs the hospital, think stopping "life-sustaining treatment" is in the youngster's best interests.
Tafida's mother, solicitor Shelina Begum, and father Mohammed Raqeeb, a construction consultant, want to move her to Gaslini children's hospital in Genoa, Italy, and have organised funding for treatment.
The couple, from Newham, east London, say Gaslini is the Italian equivalent of Great Ormond Street Hospital in London, specialists there are willing to treat their daughter, and want the judge to rule that she can move to Genoa.
Mr Justice MacDonald is due to begin overseeing a trial at the High Court in London on Monday.
Mum Shelina Begum has been told Tafida has a burst blood vessel in her brain, which UK doctors do not believe she will ever recover from.
Tafida was first given 24 hours to live but her parents say she is not ready to die.
Mohammed previously described the moment when the doctors told her they would take out Tafida's breathing tube: "They sat us down and said 'look, we are taking the decision away from you, we are saying it is futile’.
"It was the first time I’d heard them use that word.
"They said 'we cannot carry on with her treatment any more.
"Therefore we will end this here, we would like you to come to terms with it. On a date we will ex-tubate her — take out her breathing tube — and that’s it. If you don’t agree, we will take you to court’."
