More than 100 Libyans demonstrated at the headquarters of the General National Congress on Thursday angry over the lack of representation of a western town in a proposed new cabinet line-up.

The demonstrators entered the premises and aired their grievances to representatives of the legislative assembly, the first elected authority after four decades of dictatorship under slain leader Muammar Gaddafi , witnesses said.

"More than 100 protesters from Zawiyah demonstrated at the General National Congress today because they don't have representatives in the (proposed) cabinet," said Salah Hassan who holds a seat in the 200-member assembly.

"The congress is still running and we are meeting today," he added.

GNC representatives are discussing on Thursday the government line-up presented by elected Prime Minister Mustafa Abu Shagur, which omitted members of the main liberal coalition. The assembly will vote on each individual minister.
