Anna Wintour is set to "leave her job as Vogue Editor-in-Chief this summer" after 30 years at the helm

Anna Wintour, 68, who has been the Editor-in-Chief of Vogue since 1988, is set to leave her role before the end of this year.

According to Page Six, Wintour will depart Vogue and Condé Nast - where she has served as artistic director since 2013 - after the July wedding of her daughter Bee Shaffer, 30, ending her time at the company with the publication's iconic September issue.

Page Six reports that there is nobody currently in place to take over her wider role as Condé Nast's artistic director.

Though sources insist that Wintour's time at the high-fashion magazine is coming to an end, Condé Nast has rebuffed the claims.

A spokesman for Condé Nast told Page Six: "We emphatically deny these rumors."

Condé Nast 's denial has not stopped speculation, however, that it has a replacement lined up for Wintour. Sources allege that Vogue UK Editor-in-Chief, and former fashion stylist, Edward Enninful, 46, is a frontrunner to take over the position at the US publication.

Sources allege to Page Six that Wintour's ousting may be the work of Jonathan Newhouse, chairman of Condé Nast International. Newhouse, who is currently based in London, is expected by many insiders to be preparing for a move back to New York City in order to take over as Chairman of Condé Nast after the October death of his cousin Si Newhouse, who held the position for more than 40 years.

Si Newhouse was a long-time fan of Wintour's, and supported her throughout her time at the company. However, one insider told Page Six that Jonathan Newhouse "doesn't like [the amount of power] Anna has" within Condé Nast and is eager to see Enninful take over.
