The opposition proceeded with their planned gathering at Dataran Petaling Jaya here today despite not giving police notice as required under the Peaceful Assemblies Act 2012.

The assembly which began at 4.30pm was mostly attended by participants who were dressed in all black with some bringing along their babies and children.

Some carried placards with provocative words.

Among those present were Parti Keadilan Rakyat (PKR) advisor Datuk Seri Anwar Ibrahim, PKR deputy president Azmin Ali, PKR vice-presidents Tian Chua and Nurul Izzah Anwar besides PKR strategy director Rafizi Ramli.

It is also understood members of movements like Soladiriti Anak Muda Malaysia, Suara Rakyat Malaysia, Parti Sosialis Malaysia and Jaringan Rakyat Tertindas joined in.

Prior to this, police had said they had not received any notice on the planned assembly.

The act requires at least 10 days notice be given before an assembly can be held.
