New York (AFP, NYTimes, Reuters, WP) - The repercussions of mogul Harvey Weinstein's downfall are spreading further beyond Hollywood as more powerful men lose jobs over sexual harassment.

Nearly three weeks after accusations against Weinstein surfaced, leading fashion photographer Terry Richardson has now been blacklisted by some of the biggest magazines in the world, prominent editor Leon Wieseltier has lost a new magazine job, and celebrity chef John Besh has stepped down from his company.

It has also emerged that two male senior executives at a blue-chip finance company were recently dismissed for allegedly harassing associates.

It was revealed on Tuesday that Conde Nast had barred Richardson, a photographer known for sexually explicit images, from working with its magazines after years of accusations of sexual misconduct.

Wieseltier, a prominent editor at The New Republic for three decades who was preparing to debut a magazine this autumn, apologised on Tuesday for "offences against some of my colleagues in the past" after several women accused him of sexual harassment and inappropriate advances.

As those allegations came to light, Laurene Powell Jobs, a leading philanthropist whose for-profit organisation, Emerson Collective, was backing Wieseltier's endeavour, decided to pull the plug on it.

The resignation of Besh, who became a symbol of the rebirth of New Orleans after Hurricane Katrina levelled the city, was announced on Monday after more than two dozen women alleged his company fostered a culture of sexual abuse.

Twenty-five women told the New Orleans Times-Picayune they were victims of sexual harassment while working for the Besh Restaurant Group.

Besh acknowledged an extra-marital affair, but denied allegations and knowledge of sexual abuse.

In the male-dominated world of American finance, Fidelity Investments chairman Abigail Johnson on Monday urged her employees to take responsibility for their workplace culture after reports that the mutual fund company dismissed at least two money managers, Gavin Baker and Robert Chow, accused of sexual harassment.

On Tuesday, former production assistant Mimi Haleyi became the latest of more than 50 women to accuse Weinstein, alleging that he forced himself on her at his New York home in 2006, an incident that was not reported to the police and may not be prosecutable.
