“You will need to ask the Barisan Nasional chairman (about that),” he told reporters, referring to Ahmad Zahid Hamidi, who is also the deputy prime minister.

“PH is not involved.”

Anwar said this when asked to comment on Monday’s rally, which will see the participation by four different parties.

PAS secretary-general Takiyuddin Hassan had earlier issued an internal party memo saying the rally will focus on Najib’s appeal for leave to commence judicial review proceedings over the purported royal addendum.

The memo also called for party members to gather for prayers and speeches at the Palace of Justice in Putrajaya at 9am.

More than 200 busloads of Najib’s supporters are also expected to attend the rally, comprising Umno and PAS members.

Yesterday, MIC deputy president M Saravanan said “thousands” of party members will attend the rally, while People’s Progressive Party secretary-general Inder Singh Beant Singh said party members would also be present.

Najib is currently serving a six-year prison sentence, halved by the pardons board from the initial 12 years, following his conviction in the SRC International case.

The rally is being held on the day the Court of Appeal will hear his application for leave to adduce fresh evidence in his appeal to serve the remainder of his jail term under house arrest, an order which he claims was issued in a supplementary decree to the Feb 2 announcement.
