Head of civil service and MI6 chief resign Garrick membership

Exclusive: Top civil servant Simon Case follows Richard Moore in announcing decision to quit male-only club

• Members list reveals roll-call of British establishment
• Garrick Club remains a bastion of male elitism
• Legal profession's most powerful among members

The head of the civil service, Simon Case, and the MI6 chief, Richard Moore, have resigned their memberships of the Garrick Club after intense criticism of their decision to join a club that has repeatedly blocked the admission of women as members.

Their resignations come two days after the Guardian published for the first time details of the club's closely guarded membership list, revealing that fellow members include judges, scores of senior lawyers, the head of the civil service, leaders of publicly funded arts institutions and King Charles.
