Despite their long-cherished slogan of "There must be no democratically legitimised party to the right of CDU/CSU", the Union has had a serious competitor to its right since 2013. The right-wing populist Alternative for Germany (AfD) was founded with the involvement of disgruntled CDU members. It drew on the discontent of some conservatives with the Merkel administration's handling of the European debt crisis (2009–14) and later the 2015 refugee crisis, lamenting a purported loss of sovereignty and control or even "state failure". Nearly 10 percent of early AfD members were defectors from the CDU. In the 2017 election, the CDU and CSU lost a large portion of their voteshare: With 26.8 percent of party list votes, the CDU received its worst result since 1949, losing more than fifty seats in the Bundestag (despite an enlargement of the parliament). After failing to negotiate a coalition with the FDP and Greens, they continued their grand coalition with the SPD. In October 2018, Merkel announced that she would step down as leader of the CDU that December, but wanted to remain as Chancellor until 2021.
