Faberge eggs become symbols of power in new Russia

The jeweller and entrepreneur Carl Faberge fashioned his eponymous eggs from gems and precious metals in his St Petersburg workshop a century or so ago. The first one was presented by Tsar Alexander III to his wife, the Empress Maria Fedorovna, at Easter in 1885, an annual tradition which his son Nicholas II also followed with eggs for his mother and wife each Easter Sunday.

Of the approximately 50 eggs made for the imperial family between 1885 and 1916, 42 have survived.

Nine of them are owned by Viktor Vekselberg, an oil and gas tycoon who, with a fortune estimated at $18bn, is often described as Russia's richest man.

Newsnight's Stephen Smith went to meet him.
