AMMAN: Bowing to popular demands for reform, Jordan's king says future Cabinets will be formed according to an elected parliamentary majority.

Jordanians have been demanding that King Abdullah II loosen his absolute grip on power, which includes appointing prime ministers and Cabinets.

In a speech Sunday marking his 12th year as Jordan's ruler, Abdullah also promised further constitutional changes, but did not elaborate.

In six months of pro-democracy protests, Jordanians have also demanded a new parliamentary election. They claim November's election was marred by fraud.

Abdullah promised more reforms but warned that sudden change could lead to ''chaos and unrest'' like in other Arab countries.
