A widow of Indian billionaire and friend of Prince William is embroiled in a bitter inheritance row with her in-laws after her husband 'swallowed a bee' and died.

Sunjay Kapur, 53, collapsed in front of horrified teammates during a game at Guards Polo Club in Windsor on June 12.

Indian-born Mr Kapur is thought to have been stung in the mouth by a bee, which caused an allergic reaction and then a fatal heart attack.

The businessman was the heir to a car parts giant founded by his father and worth £2.7billion - Sona Comstar.

His shock death has since plunged the automotive empire - which is one of India's most highly-esteemed - into a bitter succession battle.
