BERLIN, March 4 (Reuters) - Members of Germany's Social Democrats (SPD) voted in favour of entering a coalition with Chancellor Angela Merkel's conservatives, German media reported on Sunday after a postal ballot.

If confirmed, the vote would clear the way for a re-run of the "grand coalition" that has governed Germany since 2013, putting an end to more than four months of political uncertainty in Europe's largest economy. (Reporting by Thomas Escritt and Michelle Martin Editing by Maria Sheahan)
