Pakatan Harapan will be promoting the Save Malaysia movement in a series of rallies.

Amanah president Mohamad Sabu said this will give a chance to all Malaysians to take part in the movement.

"This is because the March 27 gathering (called) by Zaid Ibrahim is closed-door and limited to those invited only," Mohamad, better known as Mat Sabu, told a press conference at the Opposition's office in Parliament today.

The first rally will be held at the Majlis Perbandaran Ampang Jaya field on March 23.

A subsequent rally will be held in Gelang Patah, Johor, on April 16, and in Kedah on May 7.

Mohamad said invitations to the March 23 gathering have been extended to former prime minister Dr Mahathir Mohamad, suspended Umno deputy president Muhyiddin Yassin, and Umno vice-president Shafie Apdal.

Through the rallies, Harapan will push for the Save Malaysia movement's demands for institutional reforms and for Prime Minister Najib Abdul Razak to step down.

They also seek to secure the freedom of jailed former opposition leader Anwar Ibrahim.

Meanwhile, Mat Sabu said Harapan would also be organising a protest against the goods and services tax (GST) at Dataran Merdeka on April 2.

"The theme of the protest is 'Undur Najib, Mansuh GST' (Down with Najib, abolish the GST)," he said.

He added that there will be a grand finale for the anti-GST event on May 31 at the Kuala Lumpur and Selangor Chinese Assembly Hall, featuring all Pakatan Harapan leaders.

Asked how many attendees he expects for the rallies, Mat Sabu simply said: "A lot."
