On 20 July, May attended her first Prime Minister's Questions since taking office, then afterwards made her first overseas trip as prime minister, visiting Berlin for talks with German Chancellor Angela Merkel. During the visit, May said that she would not trigger Article 50 of the Treaty of Lisbon–the process for withdrawing from the European Union–before 2017, suggesting it would take time for the UK to negotiate a "sensible and orderly departure" from the EU. However, although Merkel said it was right for the UK to "take a moment" before beginning the process, she urged May to provide more clarity on a timetable for negotiations. Shortly before travelling to Berlin, May had also announced that in the wake of the referendum, Britain would relinquish the presidency of the Council of the European Union, which passes between member states every six months on a rotation basis, and that the UK had been scheduled to hold in the second half of 2017.^[151][152]
