Police investigating the fire at Grenfell Tower have confirmed the cause of the blaze which killed at least 79 people.

Metropolitan Police Detective Superintendent Fiona McCormack said the fire was started by a faulty Hotpoint fridge freezer.

The investigation may bring about manslaughter charges as she revealed insulation and tiles on the tower block ‘failed safety tests’.

She said: “We are looking at every criminal offence from manslaughter onwards. We are reviewing every company involved in the building and refurbishment.”

Tests carried out as part of the investigation were ‘small scale’, and she added:

“All I can say at the moment is they (tiles and insulation) don’t pass any safety tests.

“What we are being told at the moment by the Building Research Establishment is that the cladding and insulation failed all safety tests.”

The Mirror said there were ‘600 emergency calls’ made to the emergency services on the night of the fire and police said they have listened to ‘all of them’ in their investigation.

A charity single to raise funds for those affected by the tragic events has reached the top of the streaming charts and is the biggest opening day of any single this decade.

Simon Cowell who was responsible for organising the recording, chose the song ‘Bridge Over Troubled Water’ which was originally made famous by duo Simon and Garfunkel.
