Earlier on we highlighted some key points following a statement to press from deputy chief fire officer Nathan Travis.

Here is the full report he made to the press:

A major incident has been declared at Didcot Power Station following the partial collapse of a building.

There was a partial collapse of a large building, which is approximately 300m long and ten storeys high. The building was due to be demolished in the coming months.

Oxfordshire Fire and Rescue Service has command of the incident, supported by South Central Ambulance Service and Thames Valley Police.

Sadly, one person has been confirmed to have died during the incident.

Meanwhile, four people have been taken to the John Radcliffe Hospital in Oxford; two with serious injuries, two with minor injuries.

There are three people reported missing on site at this time.

More than 50 people were treated at the scene for dust inhalation, and have since been discharged.

The Health and Safety Executive has been informed and will conduct an investigation, which will be supported by Thames Valley Police.

There is currently a 100m cordon in place, however there are no public road closures at this time.

The search will be a considerable undertaking due to the instability of the site. We expect the search will continue through the night and possibly into the coming days.

There is Specialist Rescue and Command Support Units, and Urban Search and Rescue Units from Buckinghamshire at the scene, including search dogs. The fire service is being supported by South Central Ambulance Service and Thames Valley Police.

Dust from the collapse covered a considerable area but I would like to reassure the public there were no hazardous materials within the building, we would advise local residents to remain inside, keeping doors and windows closed.

Anyone concerned about dust inhalation should call NHS on 111.

I would like to confirm that this is not being treated as a terrorist incident.
