United States to help the young man forget a failed romance. When Criticos saw an unshaven man in coveralls entering the hotel, he called out to the man to stop him. When the man turned to face Criticos, he recognised him as King Boris of Bulgaria, who was a railroad buff and was returning from driving a special train. Later history The social scene changed dramatically in London in the 1960s, with Beatlemania and the sexual revolution, and British aristocracy in the capital was not what it had been. By this time the general impeccable standards of the Ritz had fallen. Peregrine Worsthorne noted the change: "Precisely that it was not all Ritzy, in the sense of being conspicuously luxurious...the glitter had long since faded and shabbiness set in. The place was usually empty, kept alive by memories of former glories and a clientele who preferred nostalgia to comfort". Yet celebrities often held parties at the hotel, and the Rolling Stones were guests for many years.

In the 1970s, the hotel fell into a turbulent period. Terrorist threats from the Provisional Irish Republican Army became the chief concern, and bomb scares were not uncommon. The oil crisis in the early 1970s directly affected business and prompted the Bracewell-Smith family to sell their stake to Trafalgar House on 5 April 1976 for £2.75 million.

In 1984, the Ritz brought back its weekly Sunday tea dances which were popular during the 1920s and 1930s. Because of demand, the hotel considered restricting afternoon tea at the Ritz to hotel guests only, as those staying at the Ritz were often unable to get a table. Many Londoners who would have been barred by this restriction voiced disapproval and the Ritz compromised by requiring reservations for afternoon tea at the hotel. Proper attire for tea is a must; the Ritz once refused to admit Mick Jagger for tea because he was not wearing a jacket and tie. The Barclay twins of The Ellerman Group of Companies purchased the hotel for £80 million from Trafalgar House, in October 1995,
