We are almost certainly looking at a disaster as bad as Hillsborough here. My thoughts and prayers are with the many caught up in this.
It is clear that this fire ended up as awful as it has been due to someone failing to follow fire safety procedures somewhere, almost certainly to a criminal level.
A public inquiry is the right thing to do and in the meantime, these tower blocks need to be made as safe as possible.
In the future, they need to be replaced by buildings fit for purpose.
