Rolet’s return
The City’s most notorious figure last year was undoubtedly Xavier Rolet, but this year expect the former London Stock Exchange Group chief to be linked to a string of major jobs in global finance. He is already being touted by some, for example, as an adviser to the Saudi royal family on the largest stock market flotation of all time (although - and here's my second forecast - London will miss out on the Saudi Aramco IPO); but Rolet will also be sounded out for less obvious roles, including the chief executive's berth at the Commonwealth Bank of Australia.
