The police force is expected to battle with Umno Youth and polls reform coalition Bersih in the streets of Kuala Lumpur as both groups seek to break the blockade to mount two separate protests.
Umno Youth, which is rallying to defend the electoral system, will be congregating in Bukit Bintang at 1.30pm. This was a last-minute change from the earlier announced time of 10am.
Bersih has vowed to gather at the Stadium Merdeka at 2pm to call for wide-ranging reforms to the electoral system which it claims to be unfree and unfair.
Despite roadblocks at key junctions and roads in Kuala Lumpur, traffic is smooth from the low number of vehicles, but traffic is gridlocked at the outskirts as police weed out possible protestors.
The majority of the police are stationed at the favourite haunts for protestors - Dataran Merdeka, the Masjid Jamek area and the Sogo shopping centre.
Vehicles entering this area are being vigorously inspected. There is also heavy police represence at Masjid Negara.
As of 8.30am, LRT services are operating as usual, without any stations inaccessible.
The weather forecast for Kuala Lumpur is a mix of cloud and sun with the possibility of showers or thunderstorms.
Umno-owned Utusan Malaysia kicked off the day with a screaming front-page headline in bold red 'Curfew in KL today?', followed by 'There are people planning to open fire and blame the police for it'.
