BERLIN (Reuters) - Germany's Greens are open to working with any party except the right-wing Alternative for Germany after a September vote but will list gay marriage as a condition, which could make it tricky to work with Chancellor Angela Merkel's conservatives.
The Greens, which also named climate protection as their price for participating in government, could be a kingmaker in three potential coalitions after the Sept. 24 election, although recent polls have shown their support slipping to between 6.5 and 8 percent after spending much of last year above 10 percent.
