Four mock polling stations will open from September 4 to 6 to help voters familiarise themselves with voting procedures in the upcoming Legislative Council Election on Sunday.

The stations are in the Leighton Hill Community Hall, Kowloon Park Sports Centre, Tuen Mun Town Hall and Tai Po Community Centre. They will open from noon to 8pm tomorrow, Friday and Saturday.

Electoral Affairs Commission Chairman Justice Pang Kin-kee today reminded electors to follow proper voting procedures in the election.

"Electors should take their Hong Kong Identity Card to the designated polling station specified on the poll card," Mr Justice Pang said.

A geographical constituency elector should use the stamp provided to tick inside the circle of the chosen list of candidates, and fold the ballot paper inward in half before putting it into the blue ballot box.

Ballot papers for functional constituencies should be put into the red ballot box, face down without being folded.

To protect the secrecy of votes, voters should not use mobile phones or pagers, take photographs or video or audio recording inside polling stations.
