U.K. Prime Minister Keir Starmer traveled to Paris to attend French Armistice Day celebrations alongside French President Emmanuel Macron.

British Prime Minister Keir Starmer and French President Emmanuel Macron, leaders both of nations with nuclear arsenals, were in Paris under the iconic Arc de Triomphe, where dozens of wreaths were touched by a milky light and the eternal flame flickered to honor sacrifices of unknown French soldiers who perished in the first global conflict.

The King oversaw the annual Remembrance Sunday service, flanked by an unprecedented eight former prime ministers.

Sir Keir Starmer said he was honoured to pay tribute to the fallen of the First World War alongside Emmanuel Macron.
