Umno minister Noh Omar today admitted that he still does not know who 'Malaysian Official 1' (MO1) is.

This is despite fellow minister Abdul Rahman Dahlan having already confirmed that the person mentioned in the US Department of Justice (DOJ) civil suit on 1MDB is Prime Minister Najib Abdul Razak.

Noh, who is also Selangor BN chief, confessed he was in the dark about MO1 when responding to a question about Institut Darul Ehsan's (IDE) survey, which found that 40 percent of BN supporters in Selangor want the government to act against MO1.

He initially fell silent when the question was posed to him.

When pressed for a second time, Noh's press secretary told the urban wellbeing, housing and local government minister that he did not have to answer the question.

However, Noh finally replied: "I too do not know who is Malaysian Official 1. Go and ask DOJ about that."

His brief and hesitant response contrasted sharply with his earlier eagerness to respond to a previous question on the survey's other finding – that voters in Selangor's Malay belt still supported Najib, despite the 1MDB scandal.
