An investigation has been launched into allegations that unauthorised people were allowed to watch procedures being carried out in hospital operating theatres.

"I set up my whole life before I went into the operating theatre knowing that, if I didn't make it, the kids would be OK," she said.

The medics have been sleeping in the operating theatres, she says.

Tracy Turner, 51, of Roath, Cardiff, an operating theatre assistant at University Hospital of Wales, in Cardiff, has pleaded not guilty to eight charges.

Over the summer, two of the main operating theatres were out of action, disrupting care for patients needing hip and knee surgery.
