72 people died, dozens more were injured. Since then, survivors and victims' families have endured a long wait to understand exactly what happened. Today, they finally got answers. The report says the people killed in the fire were badly failed at almost every level by successive governments, companies, and the authorities through incompetence, dishonesty, and greed. All of the deaths were avoidable. Now, the families of those who died want justice. Our first report tonight is from Tom Simons. A warning, it includes images of Grenfell Tower on fire.

There have been seven years of mournings over Grenfell with no definitive answers to the question, why did this happen? Today was different. But this is how it all began. A fridge caught fire. The owner called 999, then got out, then turned on his camera. Thirty-one minutes later, flames reach the roof, then, unstoppable. Buildings are designed to prevent fire spreading. As these pictures show, this one totally failed. Nick Burton was among the few rescue, guided to safety. I don't actually remember coming out into the light.

I don't remember being handed over.

I don't remember when I took my first real breath.

I know that I thought I was going to die and melt at some stage in the tower.

They call that the Grenfell Cough, but he lost his wife, Pilar, after the fire. She was the last of its 72 victims. This was the final conclusion of the chairman of the seven-year public inquiry.

The simple truth is that the deaths that occurred were all avoidable, and those who lived in the tower were badly failed over a number of and in a number of different ways by those who were responsible for ensuring the safety of the building and its occupants.

The largest group representing victims of the fire have always said exactly that. Human life was never a priority, and we lost friends, neighbors, and loved ones in the most horrific way through greed, corruption, incompetence, and negligence. If you're looking for the one person or company that might have been to blame for the deaths of 72 people at Grenfell, you won't find it in this massive seven-volume report, because this was a failure of the system at all levels across the board. It started at the top with governments, labor, and conservative. They were warned, fires involving flammable cladding over 18 years. Six died at Lackanel House in South London, but ministers and civil servants didn't change the regulation regulations governing building materials. In 2010, David Cameron and nick Cleggs' government wanted a bonfire of regulations to help businesses. In the run up to Grenfell, the inquiry says matters of safety were ignored, delayed, or disregarded. In 2016, the aging West London block was refurbished with new cladding to make it look good next to a newly constructed school. But look at the design, sheets of aluminum and plastic shaped into square boxes. A multinational, Arconic, made the sheets.

It didn't come up with the design, but it knew the box shape was extremely dangerous, according to the inquiry. It had commissioned tests and found the boxes collected malton plastic. Yet this was deliberately concealed from the construction market, and Arconic must take responsibility for the use of cladding at Grenfell, the report says. A host of contractors were involved in the work itself, including an architect Studio E, a cladding installer, Harley Facades, and a project manager, Ryden. They were incompetent, the inquiry found, and passed the buck when it came to safety. That night, firefighters had to improvise a plan to evacuate Grenfell when the fire got out of control. No one, the inquiry said, appeared to have thought they needed to be trained. The London Fire Brigade said today that's changed, and hundreds of lives have been saved. In the Commons, this was the Prime Minister's response.

I want to start with an apology on behalf of the British State to each and every one of you, and indeed to all of the families affected by this tragedy. It should never have happened.

The Prime Minister visited Grenfell two weeks ago without any publicity, leaving a reef. Today, he said it was imperative there was a swift police investigation, and he went further.

I can tell the House today that this government will write to all companies found by inquiry to be part of these horrific failings as the first step to stopping them being awarded government contracts. We will, of course, support the Metropolitan Police and the prosecutors as they complete their investigations.

No charges are expected until the end of 2026 at the earliest, nearly 10 years after Grenfell. Tom Simons, BBC News.

All the families of those who died have finally been told what led to the disaster. Now they want justice. But what they don't know is whether anyone will be held to account and face criminal prosecution. Seven years on, victims, families, and survivors are still trying to come to terms with what happened here. Our special correspondence, Lucy Manning, has spent the day with some of them.

Sakeena Afrassahabi, Fatimah Afrassiabi.

Seventy-two names, and one of them, Khadija Khadija Khaloufi is theirs.

Khadija Khaloufi.

Their daughter, sister, and aunt.

Khadija was a joyful person.

My sister is always smiling. She always have a positive attitude.

How does it feel to hear that your sister and the other deaths were avoidable?

When you're hearing that everything was avoidable, and you heard also because of their dishonesty, you have anger inside you. You said, What are they waiting for? To make charges, to make criminal prosecution, manslaught, to give us justice. And this is what we want.

1,700 pages that amplify injustice, grief, and fury.

We are traumatized. We are empty inside now. Seven years, justice delayed, justice denied. We were robbed our right for this justice.

It's thought 52-year-old Khadija went to check on another family as she tried to escape. She never made it out the building.

We want to speak about Khadija as a good memory, but we speak all the time Khadija was burnt. Khadija died in that circumstances. So we are hurting ourselves.

We started from the Crystal Tower, I guess. Yeah, what flight are you in?

183.

We tried to get out.

Marcio and Andrea Gomez and their two children were trapped on the 21st floor. This was their 999 call. They survived, but Andrea was seven months pregnant, and baby Logan was still born.

We knew exactly what our truth was. It's great to see it now in black and white written down. But you can see there from the fraudulence, the greed, the dishonesty that was going on.

Does it give you the answers about how and why your little baby died?

No, I don't think it gives me the answers of how Logan died or how anybody died. I mean, we can see there it could have been all avoidable. It's good to hear, which I already knew, Logan died peacefully. All right.

That's okay. Sorry, not soon.

I knew that from the doctor's reports, but there's something about hearing it in the inquiry as well. But it could have been all avoided. Grenfell could have been avoided in its entirety, so I'm glad he wrote that down.

Grenfell was not just a building, but a community. The babies, children, parents, and grandparents died here, the report is clear, due to dishonesty, disregard, and incompetence. Lucy Manning, BBC News.
