The public inquiry into serial killer Lucy Letby's crimes has formally begun although hearings may not begin until next autumn.

The inquiry will examine how the nurse was able to murder seven babies and try to kill six others.

It will also look at how the NHS handled the case and its response to doctors who raised concerns.

Inquiry chairwoman Lady Justice Thirlwall made her first public address earlier.

The senior appeal court judge outlined how she intended to conduct the inquiry and confirmed that work is already being carried out to gather evidence.

Lady Justice Thirlwall said: "The parents of the babies who were murdered or suffered injuries, some life-long, live with the consequences every day.

"On top of their grievous loss, they endured years of uncertainty about what had caused death or injury. For some, uncertainty remains.
