Ingvar Kamprad died in 2018 at the age of 91.

His sons inherited a minority stake in IKEA worth around $1.5 billion (£1.1bn), but the flatpack king's adopted daughter Annika wasn't so lucky. Ingvar left her a relatively paltry $300,000 (£220k), a tiny fraction of his net worth.

He left behind a thriving multinational business that has changed the way we shop. Now the world's largest furniture retailer, IKEA owns and operates 483 stores in 63 countries, generating annual revenues of around $30 billion (£23bn) a year.
