A former British politician has been found guilty of murdering his wife after she found out he had an affair with their son's partner, the mother of one of his grandchildren.
Stephen Searle, an ex-Royal Marine and a former local politician with the eurosceptic UK Independence Party, claimed he had been defending himself after his wife, 62, attacked him with a knife.
But jurors agreed on Tuesday the 64-year-old was guilty of murder.
In an emergency call recording released, Searle told Suffolk Police: "I've just killed my wife."
Prosecutor Andrew Jackson said the couple's 45-year marriage had been under strain since Searle's wife discovered her husband's affair.
He said Searle had probably put her in a chokehold, which he knew about from his military training, after "yet another" argument.
Searle will be sentenced on Wednesday.
Searle stood for Ukip in the UK's 2017 general election.
