Is lack of diversity at top of FTSE 100 bad for business?

The UK could be at a disadvantage because too few women and ethnic minorities are on the boards of its biggest firms, according to a study by recruitment consultancy Green Park.

Its figures found that of the FTSE 100's 289 senior posts - chairman, chief executive or chief financial officer - just 12 of those roles were held by women and 10 by ethnic minorities.

Raj Tulsiani from Green Park told BBC News that women featured disproportionately on non-executive boards where their influence was limited.
