Martin Schulz, leader of Germany's social democratic SPD party, speaks to delegates during an extraordinary SPD party congress in Bonn, western Germany, on January 21, 2018. Germany's divided Social Democrats will hold a crunch vote on whether to pursue a coalition deal with German Chancellor Angela Merkel's conservatives, or plunge the nation into political turmoil. At the extraordinary congress, 600 delegates from the centre-left SPD and its 45-member board will have their say on entering into formal talks for a renewed alliance with Merkel's centre-right CDU/CSU bloc. / AFP PHOTO / SASCHA SCHUERMANN
