PETALING JAYA: A battle of wits between former prime minister Datuk Seri Najib Tun Razak and Federal Territories Minister Khalid Abdul Samad has gone viral on social media.

Najib had first posted on Facebook a picture of himself and Khalid engaging in a conversation with people at a hall.

His picture was accompanied with the caption "Oh, on my left is the founder (tauke) of Harapan Coin.

"That day he was stunned when he rode the MRT (Mass Rapid Transit). As long as he is not surprised that Cameron has strawberries that's fine (Hari itu terpegun naik MRT. Jangan dia terkejut Cameron ada strawberi sudah lah)," he said on Friday (Jan 18).

Najib's post was a jab at Khalid's proposal to introduce the Harapan Coin crypto currency in July last year.

He had also made a reference to reports that Khalid was stunned and impressed by the MRT train project.

Khalid, however, was quick to parry Najib's snide remarks on Twitter.

Ada yang Pakai baju oren nak join Amanah ke nak training baju Sungai Buloh?. Kalau nak join Amanah tu maaflah... kalau Sungai Buloh tu HARAPAN cerah. ?? pic.twitter.com/lXj32SvQYB — Khalid Samad (@KhalidSamad) January 19, 2019

"Introducing, on my right, the pioneer (tauke) of 1MDB (1Malaysia Development Berhad).

"Would just like to inform, it's better to be the founder (tauke) of Harapan Coin than the pioneer (tauke) of 1MDB that stole the people's money," he tweeted hours after Najib's post.
