Zaid Ibrahim has responded to 1MDB chief executive officer (CEO) Arul Kanda Kandasamy's sarcastic swipe at the former law minister over the ANZ Bank-1MDB related suit.

Speaking at a question and answer session in Kota Baru over the weekend, Arul said he sympathised with Zaid.

“Because I know he is frustrated and a failed politician who was promised a seat in the general election.

"Unfortunately, he was sidelined because DAP will give priority to Chinese candidates as it is a Chinese-based party.

"I feel sorry for him as he is only seeking publicity," he was quoted as saying by the Star Online.

Taking to Twitter this morning, Zaid pointed out that if he is not contesting, there is no need for him to seek the limelight.

“I went to the Australian courts because I do not believe the money in Arul Kanda's boss' account in Ambank came from a Saudi prince,” he added.

Zaid was referring to the RM2.6 billion in caretaker prime minister Najib Abdul Razak's accounts, which was described as a donation from the Saudi royalty.

The former minister has appointed a Sydney-based legal firm to sue ANZ Bank in Australia to recover the RM2.6 billion, which he insisted was misappropriated from 1MDB despite Malaysian authorities claiming otherwise.

Meanwhile, Arul, who was quizzed on this, denied the allegation that the RM2.6 billion had been transferred into the prime minister's account.

"The opposition kept repeating the allegations based on the civil forfeiture suits filed by the United States Department of Justice (DOJ).

"Up until today, it has not gone to court, so their source of allegations is baseless," he added.

Arul also invited the public including opposition leaders to attend his next Q&A session which would be held in Penang on May 3.
