TUV leader Jim Allister has questioned whether Northern Ireland's chief scientific adviser should be allowed to remain in post.
The MLA asked Health Minister Robin Swann whether it is "tenable" for Professor Ian Young to play such a significant role in the pandemic response, despite the fact that a public inquiry found he misled a coroner investigating the death of a child in a Northern Ireland hospital.
Claire Roberts, who died from hyponatraemia caused by fluid mismanagement, was one of five children whose deaths were examined by the Hyponatraemia Inquiry.
In a subsequent explosive report, chair of the inquiry Mr Justice O'Hara said that Professor Young - who was appointed as an independent expert to review Claire's treatment - had misled a coroner examining the nine-year-old girl's death.
