Private members’ clubs have been a feature of London’s social scene for centuries. Once the preserve of the city’s aristocratic elite as places to network and socialise, some of the capital’s oldest clubs still only permit men. Whites’s Club, established in 1693, situated in a Grade I-listed building on St. James’s Street, upholds this tradition, as does nearby neighbour Brooks’s (established in 1762), although women are allowed entry as guests. Membership at these historic clubs is notoriously difficult to obtain, often involving a complex system of nominations from current members. And while applications for membership at London’s modern private members’ clubs can sometimes be no less rigorous, today’s newest breed of social networking spaces are very different from the traditional model.
