Lepper, leader of the Self Defence Party, asked for high state expenditure
on agriculture, education and health. His demands are reported to have
undermined the government's efforts to control the budget deficit.
His party had also opposed plans to send soldiers to Afghanistan on budget
grounds.
Prime minister Jaroslaw Kaczynski now plans continue governing without the
Lepper's party. In case this fails, new elections are likely before the end of
the year.
Lepper was also deputy prime minister since May.
