Watch live as Pope Leo XIV delivers his inaugural mass in the Vatican’s St. Peter’s Square on Sunday, 18 May, in front of world leaders and thousands of well-wishers.
Catholic convert JD Vance, who clashed with Francis over the Trump administration’s hard-line immigration policies, will lead a US delegation alongside secretary of state Marco Rubio, who is also Catholic.
Volodymyr Zelensky, his wife, Olena Zelenska, his chief adviser Andriy Yermak and foreign minister Andriy Sybiha will also attend.
Ahead of the formal ceremony, the pontiff greeted enthusiastic crowds, estimated to reach around 250,000 people today, during his first ride in the open-top popemobile.
Faithful held flags and cheered “Viva il Papa!” as Leo, the first American pope, waved back to them as he looped slowly through the square.
Leo replaces Pope Francis, from Argentina, who died on 21 April after leading the Church for 12 years.
During the inauguration mass, the pontiff will receive two signs of his pontificate — the “pallium” and the fisherman’s ring, marking his role as successor of Peter.
