The Department of Foreign Affairs and Trade has engaged an international law firm to investigate a car accident involving the official car of Australia’s High Commissioner to the United Kingdom.

The accident, which left two police cars damaged, occurred during last year’s Glasgow Climate Summit, when Mr Brandis’ car reportedly tried to catch up to Scott Morrison’s official motorcade.

The Daily Telegraph reported that Mr Brandis’ car was trying to join the Prime Minister’s motorcade on his final day at the Glasgow Climate Summit in November, when he was en route to a stakeholder breakfast.

The newspaper reported security officers in two Metropolitan Police cars saw the High Commissioner’s official car attempting to join the motorcade and took defensive measures to head off the perceived threat.

It cited a diplomatic source as saying, “George was late and was telling his driver to hurry up and catch up with the motorcade”.
