A fire broke out just after 14h at the Marriott in Grosvenor Square in London, which is home to Gordon Ramsay’s Michelin-starred Maze Grill restaurant, according to the London Fire Brigade (LFB).

Twenty firefighters are tackling the blaze in London’s upmarket Mayfair area, according to The Telegraph.

Hotel guests were evacuated after an alarm went off.

LFB said it sent firefighters from Soho, Paddington and Euston fire stations and that, at the moment, the cause of the fire is unknown.
