The 28-year-old lived alone at a flat Cheltenham, and had been unemployed for some time when his decomposed body was found face down in a bath full of water on April 17 2015.

Police could find no evidence of anyone else being in the former spy’s bachelor pad.

An inquest heard he seemed “entirely well” until 2011 when he was suspended from GCHQ over an “incident”.

He then suffered anxiety and depression but never expressed suicidal feelings.

Mum Joanna said Tomas was reinstated by bosses but left again in 2012 and was seeking a new job in Cheltenham.

He was “completely normal” when his parents last saw him around two months before his death.

Joanna said he texted on March 26, 2015. On April 17 she and husband Viktor travelled to the town but there was no response from Tomas’s phone or from the door.

Police later found the flat unlocked, something which he would never normally have done.

His wallet and mobile phones were untouched, and the flat was tidy.

A post-mortem was carried out by Consultant pathologist Dr John McCarthy, who told the hearing that the condition of Mr Bleszynski's lungs was consistent with death by drowning.

He said: "I found no disease processes or trauma that could have had any bearing on his death.

"There were no injuries that I could find externally, or to the brain.

"There is nothing to account for his drowning apart from a sudden collapse in the bath or that he may have self-submerged in order to inhale water."

He said it was difficult to say how long he had been in the water, but he estimated about two or three weeks.

A GCHQ spokesperson said: "We were sad to learn of the death of our former colleague Tomas Belszynski, in April 2015. Mr Bleszynski left GCHQ in early 2013. Our thoughts and sympathy are with his family at this difficult time."

Toxicology reports showed he had not been taking his medication for anxiety — which he was normally very precise about.
