SAARBRUECKEN, Germany (Reuters) - When voters head to the polls in the German state of Saarland later this month, they are likely to deliver an upset to Chancellor Angela Merkel that could be a foretaste of September's national election.
One of Germany's smallest states, Saarland is - like federal Germany - currently governed by a 'grand coalition' of Merkel's conservatives and the Social Democrats (SPD).
