A BBC newsreader has quit after 37 years, citing a personality clash with a fellow presenter.

News 24 anchor Philip Hayton told Media Guardian issues of "incompatibility" with co-host Kate Silverton prompted him to leave.
Silverton's agent said she was surprised by the claim and had "never had a problem with any co-presenter".
A BBC spokeswoman declined to comment but said Hayton might continue as a freelancer.
"We are delighted Kate is part of the News 24 team," she added.
The BBC spokeswoman added: "Kate is an incredibly professional and popular presenter.
"It is a matter of sincere regret that Philip has chosen to end his BBC career in this way.
"The characterisation of Kate Silverton is one that few, if any, would recognise."
The pair began presenting News 24 in the weekday 9am to 1pm slot in July.
Hayton, who has presented the One, Six and Nine O'Clock News, said that after a succession of successful pairings with co-presenters, he had quit because of relations with Silverton.

"I think incompatibility sums it up and I don't think she would disagree with that," he told Media Guardian.
"I leave without any rancour or bitterness. Life is too short for that.
"I have been at the BBC for 37 years and it is the first time I have had a problem like this. Maybe it is just the law of averages."
Silverton's agent Alex Armitage said Hayton's departure had come "out of the blue".
"People seem to like to present with her because she's such a good journalist and such a good presenter," he said.
"I think Kate is surprised because she's not the sort of person who likes to upset anyone."
He added that she was an "experienced news journalist" despite her background presenting such shows as Big Strong Boys, a daytime TV home makeover show.
"Anyone who thinks you can't do entertainment as well as news is a dreadful snob," he added.
