DAP central executive committee member Sheikh Umar Bagharib Ali has urged MPs to demand a special tribunal to investigate Mohd Sidek Hassan's claim that he once had a cushy with 1MDB, which entailed him doing nothing.

In a statement today, Sheikh Umar (above) said Sidek was the chief secretary to the government at the time, and if the matter was not addressed, the civil service's integrity would be tarnished.
