A week of high drama in Western Australian politics has culminated with confirmation that Norm Marlborough, who resigned as Small Business Minister yesterday following sensational revelations of his dealings with former Premier Brian Burke, will also quit his seat in parliament. This will precipitate a by-election in his safe southern suburbs seat of Peel, which the ABC reports could be held as early as December 16. Labor’s margin at last year’s election was 13.5 per cent; given the government’s many difficulties in recent months, that might be close enough to make it worth the Liberals’ while to field a candidate, despite the shellacking former leader Matt Birney copped for doing the same at the Victoria Park by-election in March. Otherwise, the Labor preselection threatens to be of greater interest than the poll itself. It may also have federal implications, given that the electorate is entirely within Kim Beazley’s seat of Brand.
