The Duchess of Cambridge has visited a hotel owned by the Sultan of Brunei – a man who wishes for gay people to be stoned to death.

Kate, the 32-year-old royal, slipped in and out of the underground car park of the Dorchester Hotel inside a blacked-out people carrier.

Several celebrities, like Stephen Fry, Ellen DeGeneres and Anna Wintour, have boycotted hotels owned by Brunei over the introduction of Sharia law.

The Duchess of Cambridge was attending the wedding of her first cousin, Adam Middleton. Her parents, her brother James and her sister Pippa was also in attendance.

An insider told the Daily Mail the wedding was a ‘big boost’ for the hotel at this difficult time.

‘It shows that the royals will not let the Brunei business keep them away,’ they said.

Stoning gay people to death is just one of a number of brutal punishments brought in by the Sultan of Brunei.

Others include amputation for theft and the death penalty for adultery and declaring oneself to be non-Muslim.

Despite criticism from international human rights groups and celebrities, the Sultan has said ‘people outside of Brunei should respect us in the same way we respect them.’
