The former leader of the pro-independence Caledonian Union, Pascal Naouna, has been jailed for two weeks for drink driving and being without a driving licence.
The criminal court gave him a one-year prison sentence, yet all but two weeks of it was suspended.
Naouna, who is a businessman, was found by police near his car in what they said was an inebriated state after they were alerted about an erratic driver on the road.
The territory's newspaper reported that while he was incoherent and refused to be breathalysed, a deputy mayor of a nearby town came by and picked him up.
He was later detained and jailed straight after his court appearance.
