The SNP's Health Minister is under pressure to order an inquiry into a growing safety scandal at Scotland's delayed new children's hospital amid claims it may have to be ripped down.

Opposition parties said Jeane Freeman must agree an investigation into new allegations there are major problems with the Edinburgh Royal Hospital for Children and Young People's drainage, in addition to ventilation issues that have delayed its opening.

Tam Waterson, a senior union official representing Edinburgh NHS staff, claimed the £150 million hospital may even have to be torn down and Ms Freeman was the worst Health Minister he has dealt with.

He described Ms Freeman as being "cold" and having "no empathy", and argued that she is ultimately accountable for the hospital's litany of problems.

His outspoken intervention prompted the Scottish Tories demand a full audit into the building, while Scottish Labour said there should be an independent public inquiry.
