A rich banker persuaded her disabled husband to go to India on the holiday of a lifetime – then dumped him in a slum to save money on care costs.

The 65-year-old financier showed her wheelchair-bound husband videos of palm-fringed beaches and luxury hotels to lure him into going on the trip.

She then took him to a poverty-stricken suburb of New Delhi and paid a family £1,500 a month to take him in before jetting home alone to live a life of luxury, a court in Switzerland was told.

Nine months later in September 2008, her 74-year-old husband died due to “lack of care and poor hygiene” and he was cremated and his ashes thrown into a river.

Yesterday, a court in Zurich jailed his widow for four years.

The woman, who cannot be named for legal reasons, had been paying £6,000 a month to care for her husband in Switzerland.

The crime was exposed when his Indian carers contacted the Swiss authorities to inform them the man had died.

During the trial, the woman insisted her actions had been in her husband’s best interests due to the warm climate in India.

But a prosecutor told the court: “Her act was the utterly cynical disposal of an old and disabled person to save money.

“She had even shown her husband videos and books on India to sell the trip to him as a luxurious holiday.

But instead he died alone in a strange land, without familiar faces around him.”

After a trial last year, the woman was locked up for six months.

But prosecutors appealed against the sentence and she has now been jailed for four years for kidnap.
