Parliament's Public Accounts Committee (PAC) will begin investigation into 1Malaysia Development Bhd (1MDB) on May 19, says Chairman Datuk Nur Jazlan Mohamed.

He said PAC had agreed to call Ministry of Finance Secretary-General Tan Sri Irwan Serigar Abdullah and the Director-General of the Economic Planning Unit of the Prime Minister's Department Datuk Seri Dr Rahmat Bivi Abdullah.

On May 26, PAC would call 1MDB Chief Executive Officer (CEO) Arul Kanda Kandasamy and its predecessor CEO Datuk Shahrul Ibrahim Halmi who served the company between March 2009 until March 2013.

Nur Jazlan also said the committee was unanimous in its decision to begin its own investigation against 1MDB after a special meeting on April 30.

"During the discussions, all PAC members comprising of eight Barisan Nasional and five Opposition Members of Parliament were unanimous in agreeing to call all stakeholders involved in the management of 1MDB since its inception in 2009.
