Former prime minister Dr Mahathir Mohamad said the Bersih 5 rally is the last avenue for the rakyat to express their discontent on the state of the country.
"Not only is it (Bersih 5 rally) not illegal, it has become important because other avenues have been blocked by Prime Minister Najib Abdul Razak," Mahathir said in a two-part video circulated on social media.
He also explained that the rally was not illegal because demonstrations are often held to remove leaders in many other countries that practice the system of democracy.
The latest example of a country's leader being removed through demonstrations, he said, was former Brazilian president Dilma Rousseff who was impeached.
The Bersih 5 rally tomorrow is being held to, among others, pressure Najib to resign over financial scandals involving his brainchild, the state investment fund 1MDB.
Mahathir said the people do not have a viable way to get their problems heard now as the laws in the country are no longer enforced.
"Not through police reports, not through the Dewan Rakyat and such. Pleas to the rulers have also yielded no results.
"This is the situation which has forced the rakyat to express themselves through the Bersih demonstration," he said.
Mahathir also denied that tomorrow's rally was meant to topple the government.
The rally will be held in Kuala Lumpur, as well as in Kuching and Kota Kinabalu.
Clashes are expected to occur in KL, as the red-shirts have vowed to be wherever the "yellow shirts" are.
The police have said that they will do their best to ensure there will be no clashes between the two groups.- Mkini
