The billionaire Barclay twins on Thursday night shut down their operations on Sark after the islanders decisively rejected candidates sympathetic to their views in a ballot for the island’s first all-elected parliament.

The Barclays’ decision to freeze their £5m-a-year ($7.5m) investment on the island means “scores” of employees will lose their jobs, according to Kevin Delaney, who runs Sark Estate Management for the twins and who was unsuccessful in the election.
