At least 30 people have died in the Grenfell Tower fire, police have revealed.

Metropolitan Police commander Stuart Cundy confirmed the death toll as he spoke near the scene of the devastating blaze in west London on Friday.

"I'm able to say at this point in time at least 30 people have died as a result of this fire," he said.

Mr Cundy said the victims included one person who had died in hospital.

"There is nothing to suggest at this time that the fire was started deliberately," he added.

An investigation led by a senior detective from Scotland Yard's homicide and major crime command is under way with calls for "corporate manslaughter" arrests to be made.

Mr Cundy vowed police "will get to the answer of what has happened and why", adding: "If criminal offences have been committed it is us who will investigate that."

At least 70 people, including children and entire families, have been reported missing following the devastating blaze.

Meanwhile The Queen and the Duke of Cambridge have arrived at a rest centre helping those affected by the Grenfell Tower fire.

The royal visitors are expected to meet volunteers, local residents and community representatives while visiting Westway Sports Centre, near the charred remains of the building in west London.

On Thursday the Queen paid tribute to the "bravery" of firefighters who battled the fire and praised the "incredible generosity" of volunteers offering their support.

Prime Minister Theresa May May was making a private visit on Friday morning to speak with survivors at one of the London hospitals where they are being treated.

Following the visit, the Prime Minister will chair a cross-Whitehall meeting on how the authorities can help affected communities and victims recover.

Earlier Cabinet minister Andrea Leadsom was harangued in the street as she defended Theresa May from charges that she failed to show "humanity" by visiting the scene of the Grenfell Tower fire tragedy without meeting survivors or local people.
