Brookfield Multiplex designed and built the £575m Queen Elizabeth University Hospital complex in Glasgow.

However, there have been various problems at the hospital since it opened in 2015.

Now lawyers have been instructed to take legal action against the contractor “as a matter of urgency”.

The health authority was last month placed in “special measures” after issues relating to infection prevention, as well as management and control at the hospitals.

The move followed the news of the death of two children at the Royal Hospital for Children (RHC), which is part of the complex. They died in 2017, having been treated on a ward that was affected by water contamination.
