A pamphlet defending Muhyiddin Yassin from wrongdoing is being distributed to Umno delegates, as the embattled deputy president continues to lose ground in the party.

The 28-page pamphlet, titled ‘Aku Bukan Petualang’ (I am not a traitor) includes a first-person narrative allegedly from Muhyiddin's perspective.

The pamphlets were handed out to delegates by two men who did not wish to be identified, at the pedestrian bridge between the Putra World Trade Centre and the Sunway Putra mall this morning.
