In the Scottish Parliament, Mr Sarwar said that he had seen figures which suggest there were 50 cases of infections at the Royal Children’s Hospital – part of the £842m QEUH campus – between 2015 and 2018, and a further 15 unconfirmed cases so far this year. The mother of 10-year-old Milly Main has previously said she was “100%” certain contaminated water caused her daughter’s fatal infection after treatment for leukaemia in August 2017. NHSGGC insisted it was impossible to determine the source of Milly’s infection, and those of other children, because there was no requirement to test the water supply at the time.
