The right-wing Swiss People's Party (SVP) is set to bolster its position as Switzerland's leading political force in Sunday's parliamentary elections, with the Greens tipped as the biggest losers even as climate change remains a key topic for voters. In a poll conducted by the Sotomo research institute, 36% of respondents said climate change was an important policy issue, second only to health insurance premiums that symbolize cost of living pressures. Yet in a shift to the right and a reversal of the "green wave" seen in the 2019 elections, the Greens are projected to slip 3.5 percentage points to 9.7%, according to the poll, while the SVP is forecast to gain 2.5 points to 28.1%.
