The London Stock Exchange has added two new non-exec directors — a former Citigroup banker and the chair of a key City regulatory agency — in a boardroom refresh that follows a turbulent period for the exchange.

The first of the new joiners is Marshall Bailey, a former State Street executive who chairs the Financial Services Compensation Scheme. He will also take up the chair of LCH Group, the dominant interest-rate swaps clearing house in which the LSE has a majority stake, in addition to a seat on the LSE’s group board. Bailey joins with immediate effect.
