Whistleblower sounded alarm over Vashi before jeweller's £170m collapse

The former chief technology officer of jewellery retailer Vashi is alleging that financial authorities ignored his 2022 warning the company was inflating sales and diamond stock levels; the business collapsed in April 2023 with £170 million in debts, leaving investors—including high-profile UK business figures—facing heavy losses while founder Vashi Dominguez disappeared abroad.
