Black bicorne hat is one of 20 remaining that once belonged to French emperor, who famously wore them sideways

A two-cornered hat worn by Napoleon Bonaparte during his reign as French emperor has fetched a record €1.932m (£1.69m) at an auction in Paris.

The black bicorne beaver felt hat was initially estimated at €600,000-800,000. The price reached surpassed the €1.884m paid for another of Napoleon’s hats in 2014, also sold by the Drouot auction house, a spokesperson for the company said.
