Most of the 500 richest people in the Netherlands have become even richer since last year, although 54 have seen their fortunes decline, according to the latest edition of the Quote 500 rich list.

In total, the number of billionaires in the Netherlands has risen from 47 to 51, the Quote researchers say. The combined wealth of the richest Dutch has risen 4.7% to €421 billion of which €34 billion is in the hands of the top five.

Heineken heiress Charlene de Carvalho-Heineken remains top of the list with a fortune of €12.6 billion, slightly down on last year. She is followed at some distance by Luxaflex founder Ralph Sonnenberg with €6.2 billion and Frits Goldschmeding, who founded staffing agency Randstad on €5.8 billion.

The highest newcomer on the list is Hans de Haard, whose assets are valued at €350 million by the Quote research team. His money comes from Belgian biotech firm Argenz, which makes drugs to combat muscle disease.

The drop in value of payment systems maker Adyen has had an impact on some in the list, including princess Mabel, whose wealth is now put at €330 million, less than half last year’s estimate.

The brothers Taco and Ties Carlier, who founded bike company VanMoof which has gone bust, are out of the list as are Atilla Aytekin and Umut Akpinar who founded game and advertising company Azerion.

TV maker John de Mol remains the wealthiest celebrity, with assets of €2 billion while racing driver Max Verstappen is the youngest member, in 428th place with an estimated worth of €150 million.
