Deutsche Bank boss Christian Sewing not squeamish about job cuts

Chief executive has taken drastic action that was unpalatable to predecessors

When Christian Sewing took over as Deutsche Bank's chief executive last year, the writing was on the wall for the German lender's investment bank.

Sewing has spent most of his near 30-year career at Deutsche working in commercial banking, audit and risk - not on the trading floor of the investment bank that grew to dominate the company in the 2000s and became a costly burden.
