American multinational investment bank Goldman Sachs’ London staff have been offered free sex-change surgery and fertility treatments in the latest step to encourage more women to stay with the firm.

The move, announced by chief executive Richard Gnodde in a staff town-hall meeting, comes as the bank fights to change its reputation as a conservative old boys' club.

It is understood that the new perks are aimed at helping "the whole issue of inclusiveness" in the London office, with sex-reassignment surgery and IVF treatment being added to their employee benefits plan.
