Many of the key decision-makers will be questioned about their involvement in the saga in the coming weeks as the inquiry enters its next phase.

The people expected to appear include Robert Calderwood, chief operating officer of the health board between 2006 and 2009; his successor Jane Grant, who was also later its chief executive before retiring last year; and John Brown, chairman of NHS GGC between 2015 and 2023.

Former Scottish health secretary Jeane Freeman – who called the hospitals inquiry – will also appear.

It is expected this phase of the inquiry will look at why the Glasgow hospital hospital was “not built right”, as some witnesses have claimed, and examine what was done to address safety concerns before and after it opened.

Whistleblowing will also be one of the key issues covered.

One of the senior doctors who raised infection control concerns at the hospital previously told the inquiry that chief executive Ms Grant “urged” her not to blow the whistle.

Dr Penelope Redding, a former clinical director at NHS GGC, claimed there was a profound culture of fear and bullying” at the board which put more people off speaking out.

Following this evidence, a spokesperson for NHS GGC said: “A number of staff being mentioned during these hearings will also provide evidence and will endeavour to support the Inquiry to fully establish the facts.”
