BRUSSELS — European Commission President Ursula von der Leyen is planning to travel to Australia this month to clinch a security and trade deal, according to a person familiar with the talks. Her trip will follow a meeting next week between European Trade Commissioner Maroš Šefčovič and his Australian counterpart Don Farrell in Brussels, a second person said. Both people were granted anonymity because the schedules are still tentative. The EU and Canberra are moving to revive trade negotiations
