>> Parts of the wall that once divided Berlin now pop up all over the city. Almost 30 years on from the historic events that finally united Germany. But it's against the backdrop of re-emerging divisions that Germans are now preparing to vote. A continent split by Brexit, a country divided by migration and Eurozone issues.
And, as Reuters' Noah Barkin explains, a fragmented Bundestag.>> The German politics is more divided and the German electorate is more divided. You have a party on the far right for the first time gonna make it into the German parliament most likely. You have also have a party on the far left.
They've been around for a while. Together those two parties could win up to 20, 25%.>> This fragmentation could mean a number of possible coalitions come Sunday night.
Few dispute that Chancellor Angela Merkel will win her fourth term. Latest polls put her popularity at 63%. But who will rule with her under her CDU party? It could be a repeat of the current grand coalition with the SPD Social Democrats, but it's been an uneasy coupling and opposition leader Martin Schulz may not agree to it again.
That would leave the door open for FDP Free Democrats, the Greens or a combination of the two. A so-called Jamaica coalition.>>
One of Sunday's most anticipated outcomes will be the success of the far right. Merkel's decision to open Germany's doors to over a million migrants sent some moderate right wingers into the AfD's arms, boosting the anti-immigration, anti-Islam party, which has been polling at around 10%.
And handing the AfD a political voice that could impact Germany's leadership on the European and international stage.>> Some people held up Merkel after the election of Donald Trump as the defender of Western liberal democracy in the world. So what happens in Germany is important for the rest of the world.
On free trade, economic issues, but also on security and migration issues.>> It will be the last hurdle in a heavy year of European elections. The Netherlands, France, and Britain, all held big noisy votes symptomatic of current political volatility across the EU. Many now looking to Germany and whoever ends up leading it to navigate the stormy waters ahead.
