The future of Royal Bank of Scotland’s most senior European investment banker is in doubt after sources familiar with the situation questioned whether he would be returning to the bank after a three month leave. He was involved in a skiing accident over the Christmas break and has not yet returned to work.

Marco Mazzucchelli, global head of banking, head of Europe, the Middle East and Africa and deputy chief executive of global banking and markets, was involved in a serious accident while on a skiing holiday over the Christmas break which left him with a broken leg. He is expected to make a full recovery.
