Theresa May used a walking tour of Valletta in Malta to talk with some of the key players that will take part in upcoming Brexit negotiations.
The Prime Minister and her European counterparts visited some of the capital's historic sites during the 30-minute excursion.
Mrs May took turns to speak to German chancellor Angela Merkel, European Commission president Jean-Claude Juncker and European Council president Donald Tusk.
Mrs May chatted to well-wishers along the route from the Grandmaster's Palace to St John's Cathedral.
She admired the interior of the cathedral, before walking with Mr Juncker to the Barrakka Gardens, and then taking in the view across the bay with Mr Tusk.
She ignored shouted questions by reporters along the route.
