In a brief statement, the party’s information chief, Azis Jamman, said members are barred from taking part in the gathering in “their capacity as Warisan members”.

It has also banned the use of its logo at the protest.

However, Azis said, “we are consistent and committed to fighting corruption”.

Warisan’s announcement comes after the rally organisers pledged to go ahead with the event despite authorities prohibiting the gathering earlier.

Sabah police commissioner Jauteh Dikun was reported to have said the police decided not to approve the rally on grounds that the authorities wanted to maintain public order.

Jauteh said the Sabah government will be organising the Carnival Ria programme at the same venue tomorrow.

On Friday, Universiti Malaysia Sabah’s student representatives council also advised students to avoid the rally but said it will not stop anyone who chooses to go.

The council said some issues being raised at the rally could be against the law.

The rally organisers have said they are expecting up to 10,000 participants from all over the country to voice their protest against a corruption crisis that is alleged to have tarnished the state’s reputation.
