Controversial Independent politician Pauline Hanson is considering establishing her own political party and running for the Senate. The disclosure comes amid rumours that the Labor and Liberal parties will collaborate in an attempt to exclude her from politics. Since last week, there has been strong speculation that the two main parties will direct voter preferences to each other at the next general election, making it much harder for Ms Hanson to hold on to her seat in the lower house. While the two parties have yet to come to a formal agreement, the Australian Labor Party's national secretary Gary Gray said that 'Labor would be putting the Liberals ahead of Pauline Hanson'. Liberal Party federal director Andrew Robb said he assumed 'absolutely' Ms Hanson would be put behind Labor in Liberal preferences. However, Ms Hanson could win a Senate or upper house seat if as few as 14 per cent of the state electorate endorse her outspoken views against Asian migrants and her call for a racist immigration programme. Ms Hanson, who appears to enjoy wide grassroots support, said she could not understand why the main parties were joining forces against her. 'All I am doing is voicing the concerns of mainstream Australia,' she said, adding through a spokesman that she would shortly be releasing a detailed statement of her intentions. Her supporters have criticised the threat of a Liberal-Labor pact. Fellow Independent MP Graeme Campbell said such a deal would be 'bipartisanship as a means of disenfranchising people' and showed a 'total disregard for the voters'. Meanwhile, Prime Minister John Howard has come under renewed attacks for his failure to sufficiently denounce Ms Hanson's stance on Asian migrants. Leader of the Australian Democrats, Senator Cheryl Kernot, called the Prime Minister a wimp and accused him of having lost a 'fantastic opportunity to show a little bit of leadership'.
