FTSE 100 to lose another female boss

The FTSE 100 Index is to lose another female chief executive after Cynthia Carroll announced she is to step down as boss of Anglo American.

Her decision to quit the mining giant, which owns Tarmac and the majority of diamond company De Beers, comes days after Dame Marjorie Scardino said she planned to stand down as chief executive of Penguin books and Financial Times owner Pearson.
