Deutsche Bank CEO cancels appearance at Saudi investment summit -source

FRANKFURT (Reuters) - The chief executive of Deutsche Bank has cancelled plans to attend the Future Investment Initiative business conference in Saudi Arabia, a source close to the matter said.

Christian Sewing is the latest to boycott the three-day conference, known as "Davos in the Desert", after the disappearance of prominent Saudi journalist Jamal Khashoggi in Turkey.

Khashoggi, a U.S. resident, Washington Post columnist and leading critic of Saudi crown prince Mohammed bin Salman, vanished after entering the Saudi consulate in Istanbul on Oct. 2 to get marriage documents.

Since news of his disappearance, a number of U.S. and European companies have pulled plans to attend.

Deutsche Bank declined to comment.
