A Saudi man has been jailed for one year for calling for an end to the Muslim kingdom's guardianship system that gives men wide controls over women, local media said Tuesday.

The man, who was also fined 30,000 riyals (£6,500) by a court in the eastern city of Dammam, was convicted of "inciting to end guardianship of women" in statements he posted on Twitter and in public posters, the Okaz daily said.

He was arrested while putting up posters in mosques in Al-Hasa district calling for an end to the globally unique system that subjects women in the ultra-conservative kingdom to male control.

During questioning, police found out that the man was also behind a wide online campaign to end the guardianship system, the paper said.
