Health Secretary Jeane Freeman has been urged to "come clean" over when safety problems at a new flagship children's hospital will be fixed.

The £150m  Royal Hospital for Children and Young People in Edinburgh was due to open in early July, but Ms Freeman ordered the opening to be cancelled at short notice after it was found the ventilation system in the critical care unit did not meet national standards.

The new building was due to have opened on July 2 but no date has yet been given for when it will accept patients.

A full safety review was ordered by the Scottish Government following the discovery of the ventilation problem in a critical care ward.

Water, ventilation and drainage systems will all be assessed as part of the review.

At the Scottish Parliament on Wednesday, Ms Freeman is due to give a statement on the situation regarding the hospital.

Edinburgh Western Lib Dem MSP Alex Cole-Hamilton has tabled a question which Ms Freeman is due to answer in the chamber this afternoon, asking when the hospital will open.

Mr Cole-Hamilton said that the Scottish Government must now "set the record straight" on the issue.

His comments come as a Freedom of Information request by Mr Cole-Hamilton's party suggests that NHS Lothian spent over £62,000 in advertising the hospital's move to the new site at Little France.

The new hospital was built to replace the Royal Hospital for Sick Children.

"The Health Secretary needs to use today's statement to tell Parliament exactly what has gone wrong at the new Sick Kids Hospital and to come clean about when it's going to be fixed," said Mr Cole-Hamilton.

"Patients and staff are understandably frustrated about the lack of information on why this brand new hospital is deserted.

"Monthly costs for the unopened hospital continue to pile up at an astonishing rate and now we know a further £62,000 was spent on advertising for a hospital move that never took place.

"To make matters worse, we found at least one advert still pointing parents to the wrong place more than a month later.

"The SNP Government should take this opportunity to set the record straight on this fiasco and give Edinburgh residents a clear timetable of action.

"At the moment we're pouring more and more money down the drain without an end in sight."
