Mainstream parties were routed in an astonishing council by-election result just days before Prime Minister Gordon Brown is expected to call a general election.
The Greens' Rachel Eburne captured a Tory seat at Mid Suffolk District - delighting her party leader Caroline Lucas while humiliating the Liberal Democrats and Labour.
She polled 61% of the vote at Haughley and Wetherden with a 33.2% net swing from the Conservatives.
Labour, which had a councillor in the ward until 2003, polled just 32 votes.
The Lib Dems, a close second last time, only managed 51.
Result: Mid Suffolk District - Haughley and Wetherden: Green 444, C 176, Lib Dem 51, Lab 32, Ukip 25. (May 2007 - C 354, Lib Dem 309, Green 122). Green gain from C. Swing 33.2% C to Green.
The result comes a week before another by-election challenge for the Green Party in a Lancaster City Council ward where they shared seats with Labour in 2007.
Green leader Caroline Lucas is seeking a General Election breakthrough for her party.
She is fighting Brighton Pavilion where party city councillor Keith Taylor polled 9,530 - 21.9% - in 2005.
Ms Lucas said: "This is a great result, with a by-election win off the Tories. Once we elect a few Greens in an area, people like what they see and it leads to even more Green councillors. It also shows our commitment to grassroots politics at a time of deep dissatisfaction with mainstream politicians."
