A soldier who collapsed during an Army fitness test on the hottest day of the year died as a result of natural causes.

Corporal Josh Hoole, 26, of The Rifles, died in July in Brecon, Mid Wales, after collapsing while on pre-course training for the Platoon Sergeants' Battle Course.

Some MPs had linked his death with the dangers of training in high temperatures, following the death of three soldiers during an SAS training exercise in the same area in 2013.

Dyfed-Powys Police said it had ended its investigation into Cpl Hoole's death after a post-mortem examination had given the cause of death as natural causes.

A force spokeswoman said: "Dyfed-Powys Police have concluded their investigation into the unexplained death of Cpl Joshua Hoole on the 19th July 2016 at Brecon, Powys.

"The investigation has revealed that the cause of death is due to natural causes and the matter has been referred to Powys Coroner Andrew Barkley."

Speaking earlier this year, Cpl Hoole's father Phillip, himself an Iraq veteran, said his son's death could have been down to an underlying heart condition.

Cpl Hoole, from Ecclefechan, near Lockerbie in Scotland, had been due to marry his fiancee, Rachael McKie, next year and was to be best man at his brother Tyrone's wedding in Edinburgh.

He was taking part in a training session as part of a course which is described as "both mentally and physically demanding".

It is run three times a year and features long marches while carrying heavy backpacks.

Cpl Hoole collapsed at about 6.30am on July 19 - when temperatures later peaked at just above 30C (86F).

The incident came just three months after the Defence Select Committee published a report calling for the Ministry of Defence (MoD) to become liable for prosecution for the deaths of armed forces personnel.

The report found that since the start of 2000, 135 military personnel had died while taking part in training exercises - 89 from the Army, 24 from the Royal Navy and Royal Marines, and 22 from the RAF.
