36-bedroom Wellesley hotel (pictured) in Knightsbridge and the five-AA-star, 268-bedroom Westbury hotel in Mayfair will join the brand in the first half of 2017 under franchise agreements with their respective owners.

Opened in 2012, the Wellesley is owned by City and Country Hotels, a subsidiary of Arab Investments. It was initially managed by Bespoke Hotels on a white label basis.

The Westbury htoel, owned by Cola Holdings, is currently being refurbished by Alex Kravetz Designs. It features the Michelin-starred Alyn Williams at the Westbury restaurant and the Tsukiji Sushi outlet, as well as Polo bar. The hotel will join the Luxury Collection on completion of the renovation next spring.

The two London hotels have been announced as new additions to the Luxury Collection alongside three other European hotels: Hôtel de Berri, Paris, France; Cristallo, Cortina, Italy; and the Alexander, Yerevan, Armenia.
