Copies of book about British monarchy changing hands on resale websites for up to €175

Dutch first editions of the book Endgame, which names two members of the British royal family alleged to have discussed the skin colour of the Duke and Duchess of Sussex’s unborn baby, are selling online for many times above the original retail price of €22.99.

As parts of the British press reached fever pitch trying to find out whether the Dutch version had contained a mistranslation, or had failed to adopt final excisions or was running a strange publicity stunt, bids for a Dutch version on Marktplaats on Thursday reached €175 (£150).
