by inspecting that the metal ballot boxes have not been tampered. They also ensure that the boxes are securely locked before voting begins. After locking, the boxes are sealed by the election commission and each agent may place their own seal on the box. The agents also ensure that the ballot papers given out to voters do not contain markings. In the past certain parties have marked the ballot papers for their own candidates. This will result in a spoilt vote which is discarded during counting. Some ballot papers have been coated with waxy surfaces to prevent voting for certain candidates. The agents ensure that these events do not occur. The last task of the agent is to ensure that, on the close of voting, the ballot boxes are still secure and the seals are intact. This may be done at a designated counting centre instead of the voting centre. The boxes are opened once the agents are certain that there is no tampering. Voting process Since 15 December 2021, Malaysian citizens 18 years old and above are automatically registered to vote. Voting is not compulsory. After identity verification at a voting centre, each voter receives two paper ballots, one for the parliamentary seat of the constituency and another for the state assembly seat. In federal territories, where there is no state assembly, and states whose state election is held on a different date, each voter receives only one ballot for the parliamentary seat. Each voter walks into individual booth to mark ballots while maintaining confidentiality. The voter marks on each ballot the candidate of his or her choice with a cross beside the candidate's name and party symbol. After completing, the voter folds the ballots and drops them into separate ballot boxes for parliamentary and state assembly seats. Counting and announcement of election results After the close of voting the election agents check the ballot boxes prior to opening and counting. They also monitor the counting to ensure that the total ballots are the same as the number of votes cast. This extends to checking the number of "double votes". Every ballot paper has a serial number on it and they are given out sequentially. Agents may come to check that the serial numbers match up. The counting of the ballots is done by hand. After a count at the voting centre the boxes are transported to the counting
