Jonnie Irwin planned to share a touching message with his children before he died, telling them to have the confidence that they "can do anything".
The A Place In The Sun star was first diagnosed with lung cancer in August 2020 and was given just six months to live last year.
While his children were not told just how sick their father was for a long time, it is understood that the TV presenter shared his heartbreaking dying wishes with them shortly before he died.
Last summer Irwin explained that he was planning to give a final message to his children telling them to "believe in themselves" and to look after one another.
