The accession of Romania and Bulgaria in 2007 raised the number of commissioners from 25 to 27, and after the accession of Croatia in 2013 the number of commissioners raised to 28. The United Kingdom left the EU on 31 January 2020, and did not nominate a commissioner when the Juncker Commission ended on 1 December 2019.
With the reelection of von der Leyen as president, the other 26 member states will submit names for her to assemble a Commission and assign portfolios, pending hearings in the Parliament and confirmation as a whole. She has asked for female and male candidates, as she did throughout her first commission.[citation needed]
A number of commissioners were formally nominated and assigned portfolios before being withdrawn after their hearing with the European Parliament, with the exception of Thorvald Stoltenberg, who withdrew after the rejection of Norway's accession referendum.[citation needed]
At the end of the Juncker Commission, some were initially named by the member states to succeed commissioners who took seats in the European Parliament before an agreement to not fill the seats under the start of the next commission.[citation needed]
The Von der Leyen I Commission requested member states name female and male candidates in order to have gender parity. She would then chose the one candidate to be formally nominated, or request new names. She usually continued her request for female and male candidates for vacancies throughout her first commission.[citation needed]
