As many as 76 people could be missing following the Grenfell Tower blaze, the BBC understands.

The Met Police have confirmed that at least 17 people are dead - some of them could be among the 76 people feared to be missing.

The BBC sourced information on the missing residents through a mixture of reporting by BBC News staff on the ground, information given to the BBC from families and friends including via social media, and other media sources.

The London Fire Brigade says the search of Grenfell Tower will be "a slow and painstaking process".

In a statement, it said 20 firefighters and four fire engines, plus other specialist resources, had remained at the scene overnight and will stay there throughout today.

It added: "Three Urban Search and Rescue (USAR) modules and 30 specialist USAR firefighters are working to make the block safe so our firefighters can continue to progress throughout the building, making a detailed search."

"This search will be a slow and painstaking process which will require a large amount of shoring up work, especially on the upper floors which will be the most challenging for us to access and search."

The Today Programme's John Humphrys has asked Communities Minister Sajid Javid if enough was done to prevent the Grenfell Tower fire - especially given that a coroner's report after the 2009 Lakanal House fire had already raised concerns about cladding.

Mr Javid said things had been to done to try and prevent fires over successive governments but admitted that clearly not enough had been done.

"If enough had been done this shouldn't have happened...we need to find out what exactly happened here," he said.

He cautioned against speculation, arguing that we must wait for experts to tell us the cause of the fire.

The upper floors of Grenfell Tower are currently too unstable to be searched by firefighters or police.

At the moment drones and specialist dog units are being used to search the upper floors to find any remains.

London Fire Brigade Commissioner Dany Cotton said that the search could take weeks, and reinforced shorings would be needed for emergency services to access the upper floors.

Jolyon Maugham QC, who is offering to help Grenfell Tower residents with compensation claims for free, has spoken to BBC Radio London's Vanessa Feltz about potential legal recourse for residents.

"You can't turn back the clock and create justice but what the law can do is try to provide some financial measure of compensation," he says.

"It doesn't bring back your brother who died in a fire but what money can do, it should be made available to do.

"If evidence comes to show things weren't done that ought to have been done, it's right that people are punished for that.

"It's difficult to imagine an event where there were clearer warnings."

Why did the fire at Grenfell Tower spread so quickly and how can we be sure it won't happen again in another block of flats?

Mark Prisk was Conservative housing minister from 2012 to 2013, during the coalition government. He tells the Today Programme's John Humphrys there is a need for a "two-part inquiry", one looking at "what caused this fire and who is responsible" and the second looking at "what implications this has for other buildings".
