An inquest is due to open today after two guests were found dead in a hotel swimming pool in Hatfield Heath near Bishop's Stortford.
A man in his 30s and a woman in her 20s were found dead at the Down Hall Country House Hotel at the weekend. A post mortem examination found their deaths were consistent with drowning.
They have not yet been named at the request of their families but details are expected to be released as an inquest is opened and adjourned in Chelmsford this afternoon.
An Essex Police spokesman said: "Detectives are continuing to investigate the circumstances leading up to their deaths but are treating them as non-suspicious. Further routine tests will be undertaken and a report will be prepared for the HM coroner's inquest hearing."
