Further 10 cases of infections linked to the Queen Elizabeth University Hospital water contamination crisis

Anas Sarwar MSP said an NHS whistleblower has claimed a clinician-led probe uncovered the incidents.

They are on top of the 26 incidents revealed in 2017 by the same review, including the death of Milly Main, and on top of 23 cases in 2018 reported by Health Protection Scotland - all in paediatric cancer.

The news comes amid a Sunday Post story that the Health and Safety Executive listed problems with the way staff were trained and equipped to deal with highly contagious diseases, in November 2018.

A report in the Scottish Mail on Sunday also tells how an investigation has been launched after a third child was left fighting for their life after an infection linked to the water contamination crisis.

The latest case, which was said to have happened in September, comes after the deaths of two children in 2017.

All three were patients in a ward that was later found to have been affected by water contamination.

Jeane Freeman, Health Secretary, told BBC's Sunday Politics Scotland programme she not been shown the Health and Safety Executive report into the hospital when it came out in November last year.

Ms Freeman added ministers "wouldn't normally see" HSE reports, and added that it was about a separate part of the hospital, although she went on to say senior Scottish Government officials were now looking "very carefully" at what information comes to ministers.

"I want to change what is normal procedure so I do know about some of these matters," she said.

"I think I should be informed when the Health and Safety Executive issues serious compliance notices on any board."

She also said she could not give definite numbers on how many infection cases there had been.

Ms Freeman said: "Once I am absolutely confident of those numbers I'm very happy to give them to you, but at this point that work is still going on.

"And that is partly why I escalated that board to level four, so we can get that data and look across all the inspection reports, to be sure exactly how many children were affected."

The Scottish Government announced on Friday the escalation of NHS Greater Glasgow and Clyde (NHSGGC) to stage four of the NHS Board Performance Framework.

In Scotland, a five-stage scale is used to show the level of oversight for stricken health boards.

Mr Sarwar said: "These latest revelations from an NHS whistleblower show that problems at this hospital have been going on for years.

"It's clear that action should have been taken much earlier by senior managers to prevent the tragedy which unfolded.

"Doctors responded to concerns about the circumstances of Milly's death by starting the formal whistleblowing process in September 2017.

"Dedicated staff repeatedly raised issues about the water supply with senior management, but they weren't listened to."
