The UK Telegraph reports here:
The SPD’s decision to return to opposition has limited her options, with a three-way coalition with the pro-business Free Democratic Party (FDP) and the Greens the only obvious option.
However, the FDP is unlikely to countenance the EU reform objectives of France's Macron, and the Greens want to shut down the coal plants Merkel relies on after she shut down the nuclear plants in the wake of Fukushima, which the FDP opposes, making life very difficult indeed for Frau Merkel.
Meanwhile the anti-Islamist AfD is set to take seats in the parliament, the first time the right has been represented there since 1961.
