Peer Steinbrueck, the SPD (Social Democratic Party of Germany) leader and candidate for Federal Chancellor, speaks to supporters in front of the Brandenburger Gate. As the campaign for the 2013 Federal Election begins, the SPD held a rally they labelled the 'Deutschland Fest', an event to mark the 150th anniversary of the founding of the party. A federal election is due to take place on 22 September 2013 to determine the make-up of the 18th Bundestag, Germany's legislative body.
