A pre-inquest review into the death of a seven-year-old schoolboy is due to be heard this morning.

In February of last year Zane Gbangbola was taken to hospital with his mother Nicole Lawler, 37, and father Kye Gbangbola, 48, after being overcome by fumes when the basement of their £1m riverside property in Chertsey filled with floodwater.

The seven-year-old, who attended St George's Junior School, Weybridge, later died.

His parents believe the poisoning was from contaminated water from a landfill site near Chertsey.

Mr Gbangbola, who was paralysed from the waist down due to the hydrogen cyanide poisoning, has said of his son: "Anyone who knew our Zane will know exactly why we need to get to the truth.

“He was an incredibly bright, generous, happy and life-loving boy who had such a wonderful future ahead of him. We cannot let his death be in vain."

Police said Zane died from carbon monoxide, but his parents said this was impossible because their house was fully electric. Surrey Police investigated and found no criminal charges would be brought over Zane's death.

The pre-inquest review is to be heard at Woking Coroner’s Court.
