Dame Clara Furse, the first female chief executive officer of the London Stock Exchange, was ever present on the FN100 lists from 2006 through to 2008. She has adopted a lower-profile since resigning last year and now holds two non-executive directorships. Will that be enough for her to make this year's list, published this coming Monday?

Her career in financial services began as a broker in 1979 and, having undertaken roles spanning the global markets, including serving as group chief executive of Credit Lyonnais Rouse from 1998 to 2000, Furse was appointed as head of the LSE in 2001.
