A Spanish court has sentenced a former top banker to 18 months in jail for trying to smuggle a Picasso painting deemed a national treasure out of the country on a sailing yacht.
The court also fined ex-Bankinter head Jaime Botin 52.4 million euros ($58.4 million), according to the Madrid court ruling issued on January 14 which was made public on Thursday.
It awarded ownership of the work, "Head of a Young Girl", to the Spanish state.
Botin, 83, is unlikely to go to prison as in Spain first offenders for non-violent crimes are usually spared jail time for sentences of less than two years.
French customs seized the work, which is estimated to be worth 26 million euros, in July 2015 on the Mediterranean island of Corsica, halting what they said was an attempt by Botin to export it to Switzerland to sell it.
His lawyers argued at the time that he was sending it for storage in a vault in Geneva but the court found him guilty of "smuggling cultural goods" for removing the painting "from national territory without a permit".
Botin, whose family are one of the founders of the Santander banking group, had been trying since 2012 to obtain authorisation to export the painting.
However Spain's culture ministry refused the request because there was "no similar work on Spanish territory" from the same period in Picasso's life.
In 2015, a top Spanish court sided with the authorities and declared the work of art "unexportable" on the grounds that it was of "cultural interest".
Picasso painted it during his pre-Cubist phase in Gosol, Catalonia, in 1906. It was bought by Botin in London in 1977.
Botin's lawyers had argued that the work should not be subjected to an export ban since it was acquired in Britain and was on board a British-flagged vessel when it was seized.
When customs officials boarded the yacht, its captain only presented two documents -- one of which was the court ruling ordering that the painting be kept in Spain.
The painting is currently stored at the Reina Sofia modern art museum in Madrid, which houses Picasso's large anti-war masterpiece "Guernica".
