The hospital had a multi-layered governance structure, with a range of divisional boards and sub-committees, de la Poer outlines.
"There seems to have been significant overlap in remit between these various groups," he says, adding the inquiry will explore whether this "affected how the hospital identified and dealt with concerns raised about neonatal mortality".
He says that there were a "number of routes" for issues to be referred from groups near the bottom of the hospital’s governance hierarchy, "all the way to the board", but that's "not what happened".
De la Poer adds the inquiry will look at why the "increase in neonatal mortality and the concerns raised about Letby were rarely discussed".

The hospital board met sixteen times between June 2015 and May 2017, the inquiry hears.
Concerns in relation to Letby were only explicitly discussed at four "extraordinary meetings" held in private, de la Poer says.
On 14 July 2016, Tony Chambers, former chief executive of the Countess of Chester Hospital, informed the board that there had been an unexplained increase in neonatal mortality at the trust, the inquiry is told.
The board were told a peer review had been undertaken, which was "inconclusive" - and Ian Harvey, former medical director of the Countess of Chester Hospital, would undertake his own review of the data.
Following the meeting on 14 July 2016, the board "did not discuss neonatal mortality nor the concerns raised about Letby again until the new year," de la Poer says.
Letby’s last shift on the neonatal unit was on 30 June 2016, de la Poer had outlined.
