David Hunter, a founding director of the Northumberland Tourism organisation, collapsed last Sunday at his home after a seemingly small accident while on holiday with wife Sue in the resort of Icmeler.
The 59-year-old was rushed to hospital where specialists carried out scans before discovering a blood clot on his lung.
Despite receiving emergency treatment, the father-of-two suffered a heart attack in the early hours of Monday and he died in hospital the next day.
Mr Hunter was born in Hartlepool and grew up in Morpeth, Northumberland.
