A year has passed since a small kitchen fire in west London became the biggest and most devastating blaze in modern British history.

Today marks 12 months since a small kitchen fire in the west London high-rise turned into the most deadly domestic blaze since the Second World War.

Starting in a fourth-floor flat, flames raced through the rest of the 24-storey building in the early hours of June 14.

Some 71 people, including 18 children, died in the inferno, which prompted a giant criminal police investigation, public inquiry and painstaking recovery operation.

A female resident died the following January.

In memory

Twelve blocks, plus the tower, are expected to turn green in a show of solidarity across the west London skyline, while Downing Street is also to be illuminated.

The 13 buildings will be lit up from 00.54am on Thursday - the time off the first 999 call reporting the fire - until 5am.

For the following four evenings they will be illuminated from 8pm until midnight.

The display is one of a series of commemorations and vigils taking place this week as the public inquiry takes a step back.

Here are the key developments which could take place during the next year:

Criminal prosecutions may be brought

In an update the week before the one year anniversary, the Metropolitan Police revealed it was close to moving into a new phase of its criminal investigation.

Scotland Yard said it would be looking at interviewing potential suspects in the "near future".

Detectives are looking into possible offences including misconduct in public office, manslaughter, corporate manslaughter and breaches of fire safety regulations.

All survivors to be in permanent new homes

Leader of the local council Elizabeth Campbell said she was hoping all households displaced by the fire would be in permanent new homes within one year of the fire.

It follows an over-ambitious promise from the Prime Minister in the days after the blaze that survivors would be rehoused within three weeks, followed by a revised Government deadline of a year.

None of these targets have been met

One year on, 68 households remain in emergency accommodation, mainly hotels, 52 are in temporary accommodation and 83 are in permanent homes.

First phase of public inquiry to conclude

The first phase of the public inquiry, which is looking at what happened on the night of the fire, got under way at the end of May after seven days of commemorations.

This strand of the inquiry has been given priority so an interim report can be published as a matter of urgency, in the hope it will highlight any major safety issues which need to addressed at other high-rise blocks.

The current timetable indicates this phase will finish at the end of October.

The second - which is expected to take longer - is due to open in Spring 2019.

As part of this, the deeper cultural issues underlying the fire's causes will be put under the microscope.

Why residents' warnings were ignored, the response of Kensington and Chelsea Council and central Government in the aftermath of the fire and the work of the emergency services will be among a catalogue of issues explored.

Grenfell Tower shell could be demolished

Once the police site investigation concludes, the force will relinquish responsibility for the area - still considered a crime scene.

At this stage, it is unclear to whom.

Then, attention will turn to what should be done with the charred shell, which was once home to hundreds.

Work to cover the tower in white sheeting finished days ahead of the anniversary, with banners adorning the top four floors.

It was initially believed the structure would be demolished by the end of 2018.

The community is adamant they do not want the site built on by developers, while ideas of a memorial garden or remembrance space have been suggested.
