BERLIN/GREIFSWALD, Germany (Reuters) - German Chancellor Angela Merkel, poised to win a fourth term in Sunday's election, and her centre-left challenger Martin Schulz urged supporters on Saturday to keep fighting for votes with a third of the electorate still undecided.
Merkel is widely expected to cruise to re-election with the Schulz's Social Democrats trailing by double digits but the far-right Alternative for Germany (AfD) could emerge as the third largest party, complicating the outlook for her next coalition.
