My question is to the Minister representing the Prime Minister, Senator Brandis. I refer to former member Mr Andrew Robb and his appointment to the Chinese owned Landbridge Group less than seven months after stepping down as Minister for Trade and Investment. Given the Landbridge Group has cited Mr Robb's influence as a leading factor in his appointment, has the Prime Minister sought to clarify what role this new appointment will take and whether this represents a conflict with his previous role as a government minister?
