Meanwhile, Labour leader Jeremy Corbyn has said: "I feel absolutely for the parents.

"Any parent going through this would want their child to get the best possible treatment that could be found anywhere, and I think it is up to us to ensure they do get that best possible treatment.

"It is difficult to judge what a medical, a medically qualified person, has assessed on the case, I haven't seen that, I'm not medically qualified.

"All I can say is that any parent would feel for those parents and say if it was my child that was going through a terrible, terrible trauma like this, a life threatening trauma, you'd move might and main to get them the best treatment they can. I fully understand that."

Boris Johnson on Wednesday backed GOSH and stressed that any decisions made about his care should be in his "best interests".

The Foreign Secretary told his Italian counterpart it is "right that decisions continued to be led by expert medical opinion, supported by the courts".
