Sunday's vote followed a heated election campaign centred on the issues of migration, internal security and peace.

Brandenburg is a longstanding stronghold for the party. But it is located in Germany’s relatively impoverished east, where the anti-immigrant A f D performs far better than in the west. That made this election a test of whether the SPD could beat the populists on its home ground.

Germans in the state of Brandenburg were voting in a regional election on Sunday with the far-right Alternative for Germany (AfD) expected to finish first, building on successes in other eastern states and beating Chancellor Olaf Scholz's Social Democrats in one of their traditional strongholds.
