23-month-old Cailyn, and 22-month-old Sonny, both died on 6 December 2016 at the Royal Hospital for Children, Glasgow.

Sonny and Cailyn were not treated by the same doctors and did not encounter each other in the Royal Hospital for Children.

A preliminary hearing is set for 8 March 2024 at Glasgow Sheriff Court.

Procurator fiscal Andy Shanks, who leads on death investigations for the Crown Office, said: “The lord advocate considers that the tragic deaths of of Cailyn Newlands and Sonny Campbell occurred in circumstances giving rise to significant public concern and as such a joint discretionary fatal accident inquiry should be held.

“The lodging of the first notice enables FAI proceedings to commence under the direction of the sheriff.

“The families will continue to be kept informed of significant developments as appropriate, with regard to the welfare and wishes of those involved, as court proceedings progress.”
