The Moscow Eurovision, which at the time was thought to have been the most expensive in history, was estimated to have cost around £25m to host, while the following year in Oslo came in at around £23m.
Last year's tournament in Baku dwarfed these figures, however. Unofficial estimates said the Baku government may have spent up to £500m.
