Grenfell is the tragedy that keeps on shocking.

Not a week goes by without another revelation.

This week we have learned that not only were the panels inflammable but seemingly contained dangerous toxics.

We may never know the true number of deaths nor the exact cause of what set off the inferno.

However we already know enough to be deeply troubled by the sequence of events that occurred whether that be why dangerous cladding was installed and the slowness to respond to what is now one of the UK’s greatest tragedies alongside the Great London Smogs, Hillsborough, Bradford and Zee Brugge.

All of those led to dramatic changes in health and safety and we are all the better for that.

I have to say that I felt a degree of sympathy for Sir Martin Moore-Blick the judge who was nominated to lead the public enquiry into Grenfell.

Vilified from the announcement as being unsuitable and out of touch he has had to struggle to even get a hearing from those involved.

He will nevertheless have a very difficult responsibility for having met one of the Grenfell Action Group recently the anger and sense of betrayal is rife amongst survivors and all those affected.

They feel marginalised and insistent that the authorities have been far too slow to act and incapable of responding even to their most basic needs.

The Fire was sadly the culmination of a great deal of hurt that they have felt for a long period of time.

Finding them suitable alternative accommodation should be amongst the most straightforward of tasks yet they have been failed even on this.

There is a fear that the enquiry will take far too long to complete and will not properly associate blame.

On that a close friend who has worked in the building industry for a generation said to me if ever there was a case for corporate manslaughter this was it.

For that we will have to await the enquiry’s recommendations and any ensuing legal action.

Given how long Hillsborough has taken one is not filled with hope that there will be a speedy outcome.

For the rest we must now express empathy with the victims, their families and their community.

That this has happened in twenty first century Britain is a legacy that we will find difficult to cast off.
