The Princess Royal begins a day of engagements in the Scottish town of Lockerbie, starting with a visit to MacRebur plastic company to meet investors and employees. In 1988, Lockerbie became the scene of Britain’s deadliest ever terrorist attack when a bomb exploded on board Pan Am Flight 103 as it flew over the town. Princess Anne will pay tribute to the victims at the Garden of Remembrance later on Monday. Report by Jonesia.
