Bersatu strategy and policy deputy bureau chief Wan Saiful Wan Jan criticised BN's singular obsession with Pakatan Harapan's pledge to do away with the goods and services tax (GST), pointing out that it was only one out of 60 promises in its manifesto.

Wan Saiful noted that BN had ignored other key pledges by Harapan, particularly on institutional reforms which the ruling coalition had long resisted.

"I challenge Prime Minister Najib Abdul Razak to rebut promise number 14 which would put the MACC under Parliament and also appoint an NGO representative as a MACC commissioner and promise number 15 to separate the prosecutor's role from the attorney-general.

"Both of these are essential in ensuring the integrity and combating corruption," he said in a statement.

Likewise, Wan Saiful also challenged Finance Minister II Johari Abdul Ghani to address Harapan's pledge preventing the prime minister to also hold the position of finance minister.

"Malaysians and analysts should not be rapped in Umno's narrow narrative.

"Umno is praying that the people will only look at a single issue as it is unable to rebut all other pledges, particularly on the institutional reforms," he said.
