The grieving brother of a soldier who died on a training exercise on the hottest day of the year will read out the best man's speech which his sibling was due to give. 

Tragic Corporal Josh Hoole, 26, had already written his speech for his brother and fellow soldier Tyrone's wedding next week to fiancee Carey Taylor. 

Now Carey has revealed that grief-stricken Tyrone has decided to go ahead with the wedding in Edinburgh next week - as it is what Josh would have wanted. 

And bridegroom Tyrone, 27, has courageously decided to try and read out the best man's speech which Josh had prepared. 

Carey, 25, said: "Ty is going to read Josh's speech, if he can. He'll try his best. 

"We're all heartbroken by what happened to Josh. 

"We could have put the wedding back two months but is that going to be any easier? 

"Josh would have wanted us to go ahead with the wedding - it will let the family come together." 

And Carey reavealed that it was Tyrone who had to break the news of the death to Josh's long-term girlfriend, Rachael, 29. 

Carey, from Lockerbie in Dumfries and Galloway, said: "Ty was the one who told Rachael that Josh had died. 

"She had friends with her at the time which was a good thing in a way because she had someone there to comfort her during this terrible time." 

Corporal Hoole, from Ecclefechan in Dumfries and Galloway, had just finished an eight-mile fitness test during pre-training for the Platoon Sergeants' Battle Course when he collapsed upon returning to barracks in Brecon, Wales, on Tuesday. 

Joshua, who was on day two of a two-week course, was serving in the Rifles regiment at ITC Catterick, North Yorkshire. 

The exercise he was doing involved carrying 25kg in two hours in what was an annual fitness test and was "not supposed to be taxing". 

Meanwhile, Joshua's grandfather, John Craig, 79, has described the Brecon Barracks as a "horrible place". 

Mr Craig revealed how he himself served in the Royal Artillery and worked as an instructor at Brecon in the 1950s 

He said: "It's been a horrible accident. 

"For Josh to be in Afghanistan twice and come back and then for this to happen at Brecon Beacons... we're shell-shocked. 

"I was an instructor at Brecon in the '50s for a couple of months. 

"It's a horrible place and that was in winter. 

"The MoD have been keeping their cards close to their chest but we think it's dehydration of something that has caused this. 

"Of course questions need to be asked but if there's any blame the MoD will find out who is responsible." 

Joshua's death has come three years after three soldiers died during an SAS training exercise in the Brecon Beacons on July 13, 2013 - one of the hottest days of the year. 

A coroner ruled that neglect played a part in the deaths of Lance Corporals Edward Maher and Craig Roberts - who both suffered heatstroke - and Corporal James Dunsby - who died from multiple organ failure two weeks later. 

Corporal Hoole's brother Tyrone is a solidier in 3 Rifles.
