Sunday's German election may result in a conservative-led coalition government that faces pressure for much-needed change to revive the stagnant economy - and moves to block reform by populist parties if they do well.

The frontrunner in the race to run Germany is Friedrich Merz, whose Christian Democrats (CDU) are up to 10 points ahead in the polls. He was chosen as candidate for chancellor ahead of Markus Söder, the leader of their sister party in Bavaria the Christian Social Union.

The parties standing in the federal election are, from left to right on the political spectrum: Linke (the Left), SPD (social democrats), Greens, FPD (liberals), CDU/CSU (conservatives), AfD (right-wing extremist/populist).
