According to the rules of procedure, the two vice presidents of the House of Representatives nominate the second- and third-largest parliamentary groups - namely, the CDU and the AfD. The CDU has nominated the current Speaker of the House, Cornelia Seibeld, while the AfD's candidate is Martin Trefzer. The House of Representatives has 153 members in the new five-year legislative term - 6 fewer than before. The Left holds 45 seats. However, the caucus currently consists of only 44 members because one elected Left politician was unable to attend the caucus's constituent meeting due to illness. The CDU has 33 members, the AfD 29, the Greens 25, and the SPD 21. Just under half of the members are new to the House of Representatives. Women make up about 38 percent of the House of Representatives.
