A 10-year-old boy died in hospital while on holiday with his family in Rhodes, a court has heard.

Ronni Johnson was on the Greek island just over two weeks ago when he became short of breath.

His condition then deteriorated requiring him to need medical attention.

The boy, who has a genetic condition, was taken to Rhodes General Hospital for treatment, but despite paramedics performing CPR for an hour, he died on Monday, July 10.

The island has been in headlines in recent days for the wildfires which have caused destruction and disruption to locals and holidaymakers.

However, Ronni's death occurred before that crisis developed.

An inquest into his death opened in Norwich on Wednesday and heard that his medical cause of death was pulmonary oedema - fluid in the lungs.

The youngster, who lived in King's Lynn, would have turned 11 next week, on Wednesday, August 2.

He suffered from a genetic condition called mitochondrial disease, a complex illness which means the cells of the body do not produce enough energy.

It was the same condition that led to the death of his younger brother Freddi, who was born in 2014 and died just five days later.

That tragedy sparked his family to campaign for a charity called My Mito Mission, which promotes awareness of the condition and raises funds for research into it.

His family and the charity had been chronicling their experiences through a page called Ronni and Freddi's Mito Mission.

A memorial fund for the two brothers has now raised more than £6,000, including £1,800 since Ronni's death two weeks ago.

A post on the charity's Facebook page reads: "With heavy hearts we share some tragic news. Ronni, 10, from Ronni and Freddi's Mito Mission passed away whilst on holiday with his loving family.

"Our deepest love and condolences to [mother] Danielle, [father] Keron, [sister] Emily and all the family."

A full inquest into his death will be held in September and is expected to last an hour.
