The People's Action Party (PAP) and Workers' Party (WP) will hold the first two rallies of this general election tonight, after permits were issued by the police yesterday afternoon. Both rallies are for single- seat wards.

The PAP will hold a rally for Radin Mas SMC at the Delta Hockey Pitch in Tiong Bahru Road from 7pm to 10pm; while the WP will hold its rally for Hougang SMC at an open field in front of Block 837 Hougang Central at the same time.

Radin Mas is seeing a three-cornered fight between Mr Sam Tan of PAP, Mr Kumar Appavoo of the Reform Party and independent candidate Han Hui Hui.

In Hougang, the WP's Png Eng Huat is being challenged by Mr Lee Hong Chuang of the PAP.

A list of designated sites for election rallies - which can be held between 7am and 10pm from today to Sept 9 - was released by the police yesterday. In a statement, the police encouraged the public to take public transport to the rally sites, citing the large crowds that are expected at such election meetings.

The police also urged supporters to assemble and disperse from the rally sites "in an orderly manner" and warned that it would not hesitate to take action against anyone who is unruly or who commits any offence at the rallies.

The operation of unmanned aerial vehicles or drones is prohibited for public safety reasons. The status of the Speaker's Corner as an unrestricted area under the Public Order Act has also been revoked as of yesterday until Polling Day on Sept 11.

Exemptions for holding public entertainment activities at the Speaker's Corner under the Public Entertainment and Meetings Act will also be revoked during the same period. Those who want to organise activities there have to apply for the relevant permits and licences during this period.

The unrestricted status will be reinstated after Polling Day.
