Hayton began his broadcasting career as a pirate radio DJ, joining BBC Leeds in 1968. In 1974, he became a reporter for BBC News, covering a wide range of domestic and international news stories. He had a distinguished 37-year career at the BBC, reporting from Tehran, Iran as the 1979 Revolution took place, becoming a BBC correspondent in Washington D.C. and Southern Africa (based in Johannesburg), the latter of which involved reporting on the war in Rhodesia (later Zimbabwe), from 1980-83. He also reported from Eritrea during the war with Ethiopia and from Beirut during the civil war in the 1980s, narrowly escaping injury when the car he had been travelling in was blown-up by a land mine shortly after he had got out.
From 1988 onwards, Hayton presented the BBC's One O'Clock News nationally, as well as becoming one of the main co-presenters of both the BBC's Six O'Clock News and the Nine O'Clock News programmes. In 1989, after the latter programme's change of presentation, he became one of its main solo presenters. Following this, he left national news to become the main presenter of BBC North West Tonight, but soon returned to the main news to present on BBC World and, eventually, BBC News 24. In addition, he hosted a mid-90s BBC daytime quiz show entitled 'The Great British Quiz', which had previously been hosted by Janice Long.
In 1989 Hayton narrated Video 125's "Chiltern Take Two" drivers eye view video.
In September 2005, Hayton resigned from BBC News 24 six months into a year's contract, citing differences with co-presenter Kate Silverton. The Daily Telegraph, without substantiation and quoting an unnamed 'insider', reported that he turned to Silverton during a break and said "I don't like you". The Daily Mirror quoted another BBC 'insider' as saying that Silverton is "...pushy beyond belief. Behind her big superficial smile she can be a really aggressive, manipulative monster who always gets what she wants." Hayton merely cited "incompatibility" with Silverton as his reason and when his managers refused to move Silverton to another time slot he left. Silverton was later in the peculiar position of having to go through the morning's paper review live on air the morning the story broke, avoiding any discussion of the story and chiding her new co-anchor when he looked to refer to it. Hayton said that he left the BBC "without bitterness or rancour". Silverton continued to present on News 24 in the same weekly time slot alongside Simon McCoy.
Hayton is married to Thelma, and has one son, James, and a daughter, Julia.
Hayton describes his interests as walking, sailing and the theatre.
