A third soldier has died following a training exercise in the Brecon Beacons earlier this month.
The man, who has not been named, was taking part in a course to become an SAS reservist during one of the hottest days of the year.
Brecon and Radnorshire MP Roger Williams said he wanted to speak to the Ministry of Defence about how those who apply to join elite forces were vetted.
