Ananda Krishnan's apparent willingness to help settle 1Malaysia Development Berhad's (1MDB) RM2 billion loan has raised questions if the billionaire had been promised something in return.

The concern stems from the fact that 1MDB is a wholly government-owned company, which could have bearing on taxpayers.

As such, DAP's Petaling Jaya Utara MP Tony Pua ( left ) urged the government to disclose the full terms of the arrangement between Ananda and 1MDB.

"It must be asked, what was the agreed with Ananda for the RM2 billion loan?

"As much as Malaysians are a kind, generous and forgiving people, no one could possibly imagine any local billionaire giving a multi-billion ringgit loan to a wholly-owned government subsidiary without strings attached.

"Did 1MDB sign a loan agreement with a white knight or the devil?" Pua said in a statement.

Even though 1MDB has refused to acknowledge the matter, it has been widely reported that Ananda was loaning RM2 billion to the company to help settle its debt as it faces the risk of default.

Pua - who is also the Selangor DAP chief - said among the issues that have to be addressed are the terms of the loan, interest rate and other conditions.

He also ticked off 1MDB for boasting that it was settling its RM2 billion debt ahead of the Feb 18 deadline.

"(1MDB group chief executive officer) Arul Kanda Kandasamy ( right ) has conveniently forgotten to mention that they were granted three extensions since November 2014.

"This doesn't take into account the fact that the RM2 billion loan originated from an outstanding RM5.5 billion loan 1MDB couldn’t repay in November 2013, before being restructured into a RM3.5 billion 10-year loan and the existing short-term RM2 billion loan," he noted.

Pua stressed that Arul should live up to his commitment that 1MDB was ready for public scrutiny.

"Hence, it is critical that 1MDB remove the veil of secrecy and disclose the salient concessions 1MDB has granted to Ananda to desperately secure the RM2 billion," he added.
