Scott Ludlam blasts Tony Abbott in final speech before WA byelectionGreens senator Scott Ludlam has used his last speech in the Senate before the Western Australian upper house byelection to deliver a stinging rebuke to the Abbott government. Ludlam’s address, sardonic at times, straight at others, and delivered to the senate at 10.08pm on Monday in a near empty house, lasted only seven minutes but covered a broad range of policy areas.
