BONN A leader of Germany's Greens warned Chancellor Gerhard Schroeder on Monday that the Ecologist Party could walk out of his coalition if a controversial election pledge to phase out nuclear power was not honoured. "This is perhaps the Greens' main reason for being in the coalition," said party co-leader Antje Radcke. "If we don't achieve anything here, we must ask ourselves what exactly we want from this coalition," she told the Berlin tabloid newspaper B.Z. in an interview.

Schroeder's Social Democrats and Greens politicians are to hold an emergency meeting over the issue this Wednesday after the Greens rejected proposals that would spread the phase-out over 25 years. (Reuter)
