A “callous and cruel” woman who slit the throat of her film director sister before making off with her diamond-encrusted gold Rolex watch has been jailed for at least 22 years.
Nancy Pexton, 70, was fuelled by jealousy when she launched a “ferocious” attack on Jennifer Abbott, 69, last June 10, slashing and stabbing her 10 times at her home in Camden, north London.
