Warren Lyttle claims he killed Lisa Jane Lyttle accidentally when their $ex game went wrong.

Warren confessed to killing her but maintains that it was by accident.

He mentioned to authorities that she died in a sado-masochistic sex act that Lisa Jane had suggested, the Daily Mail reports.

Warren made the $ex game claim a couple of days later when asked to give his own account of events.

A spokesman for the Guardia Civil said shortly after Warren's arrest: "A British man who is resident in Majorca phoned the emergency services around 3.20am & confessed during the call to killing his wife. The victim was choked with a telephone cord during a row."

Speaking from her home in Neasden, north west London, Warren's mother Joan said: "We don't know how this could have possibly happened. It has left us in total shock. We're still waiting to talk to Warren to find out what went on. There were no problems in the marriage as far as we knew. They were happy."

It’s not known if Lisa Jane's family will also bring a private prosecution against Warren.
