Deutsche boss tells staff the bank is 'rock solid' as shares slide

John Cryan emails 100,000 staff to reassure them about financial health of Germany's biggest lender after shares fall 14.5% in two days

German's finance minister and the chief executive of Deutsche Bank have both attempted to allay concerns about the health of Germany's biggest lender as its shares kept falling on another day of financial market turmoil that left London's stock market at its lowest level for more than three years.

Wolfgang Schiuble said on Tuesday he had "no concerns" about Deutsche Bank, speaking shortly after John Cryan, who was appointed to run Germany's biggest bank seven months ago, sent an email to his 100,000 staff to assure them the bank was "absolutely rock solid".
