The Swedish founder of the Ikea furniture chain, Ingvar Kamprad, has died at the age of 91, the company has announced.

Mr Kamprad – who pioneered flat-pack furniture - died at his home in Småland, Ikea confirmed in a statement.

The company said that Mr Kamprad was “one of the greatest entrepreneurs of the 20th century”.

The billionaire, who was born in 1926 in Småland, founded Ikea at the age of 17.

He used some money his father had given him as a gift for performing well at school despite his dyslexia.

In the later years of his life, Mr Kamprad faced questions over his past links to fascist groups – something he admitted, but said was a “mistake”.

In a statement on Sunday, Ikea said that Mr Kamprad had “peacefully passed away at his home”.

“He worked until the very end of his life, staying true to his own motto that most things remain to be done,” it added. Mr Kamprad eventually stepped down from the company’s board in 2013, at the age of 87.

“Ingvar Kamprad was a great entrepreneur of the typical southern Swedish kind – hardworking and stubborn, with a lot of warmth and a playful twinkle in his eye,” the company said.

His company’s designs became popular in part because of their simplicity and value.

Mr Kamprad is reported to have come up with the idea of flat-pack furniture after watching an employee remove the legs from a table in order to fit it into a customer’s car.

Furniture designer Jeff Banks said that Mr Kamprad’s creations radically changed how people made and designed products for the home.

“People have tried to reproduce and copy that, but unsuccessfully,” he said.

Mr Banks added that the designs produced and sold through the retailer made good use of recyclable products, adding that Mr Kamprad was “head and shoulders above the rest”.

Mr Kamprad was renowned for his devotion to frugality, reportedly driving an old Volvo and travelling by economy class.

In a 2016 interview with Swedish television channel TV4, Mr Kamprad said that it was “in the nature of Småland to be thrifty”.

“If you look at me now, I don’t think I’m wearing anything that wasn’t bought at a flea market,” he said.

He told the channel that he built his business on a “local ethos”.

“We have Småland in the blood, and we know what a krona is – even though it is not as much as it was when we bought candy and went to elementary school,” he said, referring to the Swedish currency.

People took to social media on Sunday to pay their respects to the “greatest Swedish entrepreneur to have ever lived”.

Swedish Foreign Minister Margot Wallstrom tweeted her condolences, saying that Mr Kamprad had “put Sweden on the world map”. (BBC)
