The revelation came from a former nurse who treated returning troops. Polly Andrews, now a Lib Dem councillor, was addressing a meeting on healthcare at Stirling Lines — the SAS’s Hereford HQ.

She said: “I used to work in the sexually transmitted diseases clinic and we had a number of SAS personnel go through.

"I was overwhelmed with the success they had in finding partners in the most unlikely of circumstances.”
