The Singapore Democratic Party (SDP) has written to the Elections Department seeking clarification on several elections rules, especially those on the use of promotional material and access to counting centres .

The letter from SDP chairman Jeffrey George, which was released to media on Friday, said the party was seeking "clear, concise and written rules that will be practised by all Returning Officers". The letter goes on to outline incidents in previous elections where the party said there was confusion over procedures its polling agents and counting agents were required to follow.

"In short, the multiple standards of operations by the Elections Officials at the various Polling and the Counting centres resulted in us not being able to fully utilise our resources and ground supporters/ volunteers," wrote Mr George.

The SDP is also asking if it can play party music during campaign rallies and also if it can have a decorated campaign bus.

"We have the intention to advertise via bus wrapping advertisement on a Private Hire Bus for the nine days of electoral campaigning starting from Nomination Day for the upcoming General Election," said the letter.
