The electorate office of embattled Labor MP Khalil Eideh has been closed, the locks changed and his staff placed on indefinite leave, amid the fallout over allegations of corruption relating to an alleged printing rort.

Earlier this month the opposition, using parliamentary privilege, accused Mr Eideh – who represents the western suburbs in the upper house – of a rort in which money from his office's official printing budget was siphoned off and used to pay for ALP party memberships.

The claims remain unproved, but Parliament's presiding officers referred the allegations against Mr Eideh's staff to the state's Independent Broad-based Anti Corruption Commission.

The locks on Mr Eideh's office are believed to have been changed last week.
