Jury are currently being read the pathology reports for a number of children in the case - they have been warned that there is a lot of incredibly dense medical detail and will be provided with a glossary of terms afterwards. Dr Marnerides due in witness box later this morning

Dr Marnerides, who leads the forensic children's pathology service at Guy's and St Thomas' Hospitals, is now in witness box. He reviewed tissue samples from Child A, who the Crown say was murdered by Ms Letby in June 2015 via air injection

The medic says from his review, he found 'globules' in the veins in the lungs and brain tissue that were most likely air, he said this air 'most likely went there while this baby was alive'

Dr Marnerides was also asked to review the case of Child C, who died in June 2015. The Crown say Ms Letby murdered the five-days-old boy by injecting air into his stomach through a nose tube, making him unable to breathe.

The medic said in his opinion, on basis of all evidence reviewed Child C's sudden collapse was caused by an 'injection/infusion of air into the NG tube'

Dr Marnerides was asked to review the case of Child D, who also died in June 2015. The Crown say she too was killed by Ms Letby via an injection of air. The medic said from his pathological review, air embolism is the 'likely explanation' for Child D's death

On the case of Child I, the medic comes to the same conclusion - that she died as a result of an injection of air

To assist the jury with his findings in relation to triplet brother Child O, who died in June 2016, Dr Marnerides presented a photograph of the baby boy's liver, taken at post-mortem, to the court.

The court has previously heard that Child O died after suffering "trauma" to his liver and an injection of air into his bloodstream. The images showed a "rather large bruise" to the boy's liver that would have caused an internal bleed, Dr Marnerides said.
