# updated 10.08pm Several hours after Kedah Menteri Besar Azizan announced that Arumugam has relinquished his exco post, he said that the PKR man has also stepped down as a state assemblyperson.
Observers should get ready to attend to duties in these 2 locations -one in Perak and another in Kedah-most likely around the same time! This will be a challenge to Mafrel to run 2 observation missions in the same region simultaneously!
